Introduction

WARNING: THIS APPARATUS MUST BE EARTHED

The CPS2000 is a linear power supply which, like other linear supplies, produces DC

voltages by rectifying, smoothing and regulating AC voltages from the secondary

windings of a mains transformer. Soundcraft mixing consoles employ a number of

dc voltage supply levels in their operation and these are all provided at the output of

each supply unit.

In regulating these voltages there is considerable heat generated, the dissipation of

which is achieved through a substantial heat sink on each side of the unit. Two fans

areincorporated which draw airovertheheatsinks to provideadequateheatdissipation

for the regulators and reduce the outer case temperature.

The CPS2000 is designed for installation in a 19" rack unit, occupying 4U of rack

height. Refer to the section "RECOMMENDATIONS FOR INSTALLATION" on

Page 7.

LEDs are provided on the front panel to show the operation of the regulating circuits,

and a digital voltmeter monitors the mains supply voltage.

The CPS2000 may be linked to a second CPS2000 to provide automatic power backup

in the event of one of the units failing.

MAINS VOLTAGE SELECTION.

Special attention should be paid to the following information:

Do not change the voltage setting without first turning

the unit off and unplugging the mains lead. Ensure that

the cover plate over the mains voltage selection

switches is replaced after correct voltage selection

has been made and that the cover plate is positioned

to show the correct mains voltage.

This unit is capable of operating over a wide range of mains voltages by means of a

comprehensive set of selectable voltage settings. It is important to ensure that the

correct voltage setting has been selected for the level of local mains voltage supply,

for safe, uninterrupted operation of the unit.

There are two mains voltage selection switches behind a cover plate on the front of

the unit. Voltage selection is achieved by moving the switches using a screwdriver

blade, into the correct positions, as shown by the symbols marked on the front panel.

In this way the unit is set up for operation at one of the following ranges of mains

supply:

OPERATING VOLTAGE RANGE

It is very important to use the correct mains voltage selection. A wide operating range

of mains voltages is provided to enable the unit to function down to only 85Vrms on

the mains supply. This facility is incorporated to overcome the problems that some

power supplies have with internal regulation when operating from a poorly regulated

mains supply.

Do not operate the PSU with a consistently high (above

nominal) reading on the mains meter. Operation with

the mains higher than +10% may cause serious

damage

The mains meter is essentially a peak-reading device, as it is the peak value of the

mains waveform which is the most important factor in providing the correct mains

voltage to the power supply. For this reason, and because with long power cables it

is common for the mains waveform to become distorted, the indication of the meter

may not agree with readings taken with the usual types of quasi-RMS reading

testmeter.

Note that the meter measures the voltage actually available at the PSU, and therefore

will indicate any voltage drop on mains supply wiring.

REPLACING MAINS FUSE.

In the event of incorrect switching of the mains voltage selectors, a mains power surge

or underrated fuse value, the mains fuse in the front panel will blow and the CPS2000

will not function. Switch the ON/OFF switch to the OFF position. Check the fuse

and replace if necessary; also check that the voltage selection is correct for the mains

supply level before switching the unit ON again.

To avoid risk of fire replace only with the correct value

fuse, as indicated on the unit.

In the event of repeated failure of the mains fuse consult the Soundcraft dealer from

where the unit was purchased.

This unit contains no user serviceable parts. Refer all

servicing to a qualified service engineer, through the

appropriate Soundcraft dealer.

Recommendations for

Installation of the CPS 2000

Installation

Download from Www.Somanuals.com. All Manuals Search And Download.

Recommendations for Installation

The CPS2000 power supply is provided with front panel fixing holes for 19"

rack-mounting and will occupy 4U of rack space. Rear support should be provided

when fitted in a 19" rack.

The CPS2000 is a heavy unit (30kg,) and should be

regarded as a two-man lift. Take suitable precautions

when lifting

As with any power supply that contains a large mains-voltage transformer, it is

preferable to provide a degree of physical isolation of the unit from other electronic

equipment, particularly that which carries low level audio signals, to avoid any

possible hum pick-up. For this reason the unit is used with a long (6.5 metres) output

cable to enable it to be positioned away from the mixing console.

For the same reason, when rack-mounting it is preferable to avoid locating the unit

adjacent to signal processing equipment.

It should be noted that if a complete rack containing a CPS2000 unit is to be operated

from a different mains supply level, then the unit should be withdrawn from the rack

in order to reselect the mains voltage setting, at the same time as resetting any other

equipment.

The other important consideration when rack-mounting the unit is the need for natural

convection of air over the case and an unrestricted air flow through the unit. Note that

air is drawn in at the front of the unit and expelled through the rear panel.

Good ventilation BELOW the unit, in the floor or back of the rack, and similarly

ABOVE the unit, at the top of the rack, will ensure a path for continuous air flow.

Other equipment in the rack which is known NOT to produce a significant amount of

heat should be mounted BELOW the unit. Equipment that also relies on good air flow

within the rack (ie. most power amplifiers and other power supplies) should be given

due consideration and some space should be provided between such units and between

these and the CPS2000 unit. Forced convection, by means of a fan-tray, may be

desirable in this situation.

The CPS2000 will operate as a free-standing unit

without requiring any special cooling arrangement,

but should not be allowed to be accidentally or

deliberately covered over in any way.

Do not operate the unit with the top cover removed as

this exposes hazardous voltages.

The filters on the cooling fans must be inspected

regularly and cleaned if necessary to maintain good

airflow through the unit. This will be particularly

important if the unit is used in a dusty environment.

Finally, some consideration should be given to the earthing arrangement of the system

at the centre of which are the console and the CPS2000 (and any other Soundcraft

power supply units). The console chassis is earthed, through the mains earth, via the

power supply. When rack-mounting the CPS2000(and any other Soundcraft power

supply units) care should be taken to avoid any possible ‘ground loops’ in the system

which would introduce audible hum to otherwise clean audio signals. Ground loops

may occur where signal processing equipment, patched to the console, has its signal

earth commoned to the equipment chassis. The ground loop is formed if this chassis

and the power supply chassis are in electrical contact through the fixing rails they

share in the rack. To avoid this situation, standard isolating washers may be employed

when fixing the power supply (or supplies) or any other unit into the rack.

W A R N I N G : THIS APPARATUS MUST BE

EARTHED. Under no circumstances should the mains

earth be disconnected from the CPS2000 power supply

unit.

GENERAL

As with all electrical/electronic equipment care should be taken when handling this

unit. Avoid general mishandling and do not drop. Avoid storage and operation in

dusty locations and do not expose to corrosive atmospheres.

To avoid risk of fire do not expose this unit to rain or

moisture.

Retain all packaging for transportation in the event of the unit requiring servicing.

Retain this manual safely, along with all other relevant documents.

For touring/mobile transportation it is advisable to install the CPS2000 in a flight case

to provide mechanical protection. Refer to your Soundcraft dealer for a suitable case.

Where the CPS2000 is enclosed in a touring case, provision must be made foradequate

ventilation to the rear of the unit to ensure unrestricted supply of air for the cooling

fan.

Use only the 16 Amp mains lead supplied, no other

type is to be used.

Use only the DC output lead supplied, no other type is

to be used.

Circuit Description

INTRODUCTION.

The CPS2000 power supply provides +/-17V at 16 Amps, +8V at 1.25 Amp, and +48V

at 0.3 Amp. The main PCB (SC3804) is in LH and RH halves. The LH PCB carries

the +17V and +48V supplies. The RH PCB carries the -17V and +8V supplies. A

separate PCB (SC3817) carries the mains voltage selector switches at the front of the

unit.

THE +/- 17V RAILS. SC3804

This consists of two identical +17V supplies connected together to give +/-17V.

Each 17V supply is a linear regulator with conventional fullwave rectification and a

large (100,000uF) reservoir capacitor. This is combined with a second power supply

that powers the driver transistors, the cooling fan, and the digital mains meter. The

main series pass elements are 250W discrete bipolar transistors connected in parallel

with suitable current-sharing precautions and mounted on a fan-cooled heatsink. The

voltage reference and servo control amplifier is provided by a 723 regulator IC. The

circuitry of the +17V regulator is described in detail below:

The +17V Supply. (LH PCB)

The transformer secondary is fused by means of 32 Amp Safeclip (BS88) fuses

mounted in holders on the floor of the chassis. They are NOT intended for customer

replacement. A spare fuse will be provided, but it is stressed that these fuses will only

blow in the event of catastrophic failure, such as a major short in the wiring or a failed

bridge rectifier.

The fullwave bridge rectifier is mounted on the heatsink, at the hottest end as it is the

most heat-tolerant of the semiconductors. The reservoir capacitors are mounted by

clips on the floor of the chassis. For safety reasons, the reservoir capacitor is

discharged by bleeder resistor R9 at switchoff; this takes about 30 seconds. A red

warning LED on the PCB is on whenever the capacitor is charged. The unregulated

DC is approx +26 to +29V.

The 723 IC contains a 7.15V nominal Zener diode, defining the voltage that appears

at Pin 6. Zener references generate appreciable noise, and this, plus any ripple, is

filtered out by R10,C10. R10 is in series with the positive input of the servo opamp

(Pin 5) and is made roughly equal in resistance to the feedback divider R16,17 etc to

minimise bias-current offsets.

The feedback divider R16,17,18 & PR1 derives a fraction of the output voltage and

delivers it to the negative input of the servo opamp. (Pin 4) The negative feedback

keeps this point also at 17.15V, so the actual output voltage is determined by the

feedback divider ratio, which is trimmed over a narrow range by PR3.

The output of the servo opamp controls the output through TR8, which is an emitter

follower driving the parallel pass devices TR4,5,6. R41 is included for diagnostic

purposes, so that the current being supplied by the 723 (only a few mA) can be

measured. The power supply to TR8 is taken from the +12V supply. This has its 0V

side connected to the positive unregulated DC supply of 26 - 29V, (at nominal mains)

giving a total voltage of approx 38 - 41V for the driver; this also powers the 723 IC.

This subrail markedly reduces the minimum drop across the pass elements and

therefore increases the efficiency.

Circuit Description

Download from Www.Somanuals.com. All Manuals Search And Download.

The 723 IC is powered through R11, which allows ripple filtering by C9, and voltage

protection by DZ1,2. These Zeners are not required to reduce ripple; their function is

purely protective, preventing the 40V Vmax spec of the 723 being exceeded should

the mains voltage rise above nominal.

The current through the pass devices TR4-7 is shared equally due to the

current-sharing resistors R35-45. The drop across these at full load is approx 200mV

which is more than enough to swamp Vbe differences in the main transistors.

50 Amp Schottky diode D7 on the output allows supplies to be paralleled for

redundancy.

The Mains Voltage Meter.

The incoming mains voltage is continuously indicated on the front panel by a 3.5 Digit

Panel Meter. (DPM)This ispowered froma+5V supply derived fromthe+12V subrail

by 7805 regulator REG2.

The +5V supply is reduced to +2.5V by R30,31, and buffered by IC2-A to generate a

half-rail for the DPM input.

The incoming mains is monitored by differential amplifier IC1-A, which looks at the

voltage between Live and Neutral; this avoids problems with having one side of the

meter connected to Earth, which is often not at quite the same potential as Neutral.

The Voltage is picked off via two special BSI safety-approved 680K resistors on the

voltage select PCB (SC3817) which connect to CN3. The circuitry around IC1-A

(R21-24) gives unity gain, but the presence of the 680K resistors on the input gives

suitable scaling of the 50Hz signal.

The signal is applied to precision full-wave rectifier IC1-B, IC2-B via DC-blocking

cap C5; this circuit is biased by the +2.5V halfrail. The rectified output is smoothed

by C6 and scaled by R39 and PR1 before applying it to the DPM input on CN1 Pin

8. (IN HI)

Note the DPM has a differential input, so the cold side (IN LO, Pin 7) is connected to

the +2.5V halfrail.

The Mutual Shutdown System.

Equipment containing some kinds of op-amp is vulnerable to damage when only one

of the +/-17V rails fails, as in this case excessive supply currents can be drawn,

damaging fuse resistors on the modules.

When both 17V supplies are working normally, current flows through DZ8, OPTO1,

and across to the RH PCB. OPTO1 is on so the base drive to TR22 is shunted away

and the 723 works normally. Likewise, TR24 is kept on via R100, and ensures TR28

stays off.

If either supply fails there is insufficent voltage to keep DZ8 conducting, and current

flow ceases in the mutual shutdown line. TR22 is turned via the special supply

generated by D13, C26, and the internal node of the 723 IC3 is pulled down to ground,

turning it off. Likewise, in the -17V supply, TR28 is turned via the special supply

generated by D14, C25, and the internal node of IC4 is pulled down to ground, turning

it off.

C27,30 delay the action of mutual shutdown sufficiently to allow the supplies to start,

as they may not rise to working voltage at exactly the same rate.

Circuit Description

Download from Www.Somanuals.com. All Manuals Search And Download.

When shutdown has ocurred, the supply is reset by turning the mains briefly off and

on. R100 discharges C25 so that the circuit is ready for use at the next switch-on. The

special supplies generated by D13, C26, and D14, C25, are designed to discharge very

quickly at power-off, and it should not be necessary to turn the PSU off for more than

a second to reset it.

Overcurrent Protection.

The simplest form of overcurrent protection is the constant-current system; when an

attempt is made to draw excessive current, the output voltage is reduced so that no

more than a fixed maximum can be drawn. The high current capability of this PSU

means that constant current protection alone is not practical as the dissipation in the

pass devices is too high for the cooling system to deal with, and in the long term they

will overheat.

The standard answer to this problem is foldback current-limiting. Once again the

output voltage is reduced to prevent excessive current flow, but it is more severely

reduced so that the current flowing is not limited to a fixed maximum, but to a value

lower than that which triggered the protection originally. This greatly reduces the

dissipation in the supply in protection mode.

This system accomplishes its task, but can give trouble as the supply may work

perfectly into a resistive test load but not start into a real console load. The problem

is that a mixing console is essentially a constant-current load; as the supply voltage is

increased, almost the full current is drawn when only 2 or 3 volts are applied. There

are thus two stable states, with rails normal and the full current drawn, or with the

supply shut down to the few volts that will cause the foldback current to flow. When

the supply is switched on, it tends to stick in the second of these two states.

The CPS2000 avoids this problem by implementing constant-current protection that

causes complete shutdown (rather than foldback) after a fixed time delay. This is

described for the +17V supply; the -17V supply operates identically.

The first part of the problem is to measure the output current without dropping 0.6V

across a resistor to turn on a protection transistor. At 16 Amps the losses in this drop

would be unacceptable. Therefore supply current is measured by the voltage drop

across 0.05R resistors (R35,36 in parallel) which carry a quarter of the output current

and so drop 200 mV at full load. This is compared with a 200mV reference voltage

across R86, derived from bands-gap reference IC8 which sits on the output rail, by

differential amplifier TR18,19. When the input to TR19 exceeds the 200mV applied

to TR18, TR19 conducts and pulls down the internal 723 node at pin 13, reducing the

output voltage.

This causes current to cease in the mutual shutdown line, as described above, and after

a brief delay caused by C27,30, both 17V supplies are shut down.

ISSUE 8 operates exactly as above. The only difference is that the differential

amplifier TR18,19 has its tail fed from a negative subrail at approx -26V. This subrail

is generated from the AC input to the PCB by charge-pump C41,42,D22,23. The

resulting negative voltage is stabilised by 8V2 Zener DZ10, and applied to R73. This

keeps the tail current of TR18,19 more constant, and so maintains the

transconductance (current out for voltage in) at a higher level, giving closer feedback

control of current-limiting under extreme conditions. The RH PCB operates

identically.

Undervoltage warning.

The supply gives a warning indication when the mains voltage has fallen so low that

regulation is about to be lost. The Headroom Indicator subsystem illuminates all the

decimal points on the DPM, giving a clear signal that something is amiss.

The voltage across the pass transistors is monitored by TR3; when this voltage falls

too low, TR3 turns off, turning off TR1. TR1 collector is then pulled up to +40V by

R26, charging C7 through D5, and so turning on TR2. This connects the DPM decimal

point connections to the local 0V (actually +26 TO +29V above supply 0V) via

current-limiting resistors R32-34. The peak-hold action of D5/C7 is required as the

voltage across the pass transistors includes a large ripple content that would leave the

decimal points rather dim if they were being strobed at 100 Hz.

An identical circuit (TR9, TR10) monitors headroom in the -17V supply. The voltage

across the pass transistors is monitored by TR10. When this voltage falls too low,

TR10 turns off, turning off TR9. TR9 collector is connected to the LH PCB via

connectors CN8-CN7, and the cessation of current drawn indicates low headroom. On

the LH PCB, when this current ceases D12 anode is pulled high by R78, and TR2

turns on, illuminating the decimal points on the meter.

The -17V Supply. (RH PCB)

The actual 17V section of this is identical to that in the +17V section.

The +12V subrail circuitry is much simpler as it only provides power for the driver

TR11, the 723, and the fan. There is no mains meter circuitry here.

The Temperature Protection System.

This is designed to protect the +/-17V rails only. The +48V and +8V regulators

incorporate internal thermal protection, and in any case, their heat dissipation is very

small compared with the heatsink size. The +/-17V rails, however are vulnerable to

blocked cooling vents or fan failure, so protection is provided that shuts down the 17V

rails if the TO3 device cans exceed 100 degC.

The thermal sensor on the RH heatsink is LM35DZ TR31. It outputs 10mV per

degreeC above freezing point (0 degC) and applies it to IC5-B non-inverting input.

IC5-B is used as a comparator, with R114,106 giving a small amount of hysteresis to

prevent dither or oscillation.

IC reference TR29 produces a stable 1.237V which is reduced to 1.00V by R104,112.

This is applied to the inverting inputs of IC5-A,B as the shutdown temperature

reference, and represents 90 degC at the TO3 can top*. TR27 senses the temperature

of the LH heatsink.

* Temperature shutdown takes place at 100 degC on some earlier issue PCB’s.

If either heat sensor exceeds 100 degC the output of the associated op-amp goes high,

applying voltage to the top of R109, and enabling the relaxation LED-flashing

oscillator IC6-B. LED7 flashes at approx 2 Hz.

If JMP2 is fitted in the "ON" position, shutdown of the +/-17V rails is also

implemented. TR30 is turned on via R117, which turns on TR28, and shuts down the

-17V supply. The mutual shutdown system then also shuts down +17V. If JMP2 is in

the "OFF" position, only the LED flashing occurs.

The +48V Supply.

Max current rating is 0.3 Amps. The +48V phantom supply is based on the

high-voltage regulator TL783C. (REG1) The AC input is fused by F4 and fullwave

rectified by BR4; C1,24 are the reservoir capacitors. The unregulated DC may rise as

high as +85V on high mains.

The TL783C maintains a fixed 1.27 V between its ADJ and OUT pins, so the

adjustable voltage-divider R1-PR2-R2 gives an output of approx 48V. This can be

finely adjusted by PR2. The divider current is also used to power the rail indicator

LED3, minimising the current wasted inside the regulator circuit.

An output current of 0.5A and a wide (+10/-20%) mains range means that a TL783C

alone is only marginally capable of handling the power dissipation. Therefore

preregulator TR16,17, working as an emitter-follower biased from the +48V output

by zener DZ5, absorbs some of the voltage drop, so that only approx 62V appears on

the TL783C input. C28 ensures HF stability of REG1.

Two protection diodes are included. D1 protects the regulator from reverse voltage if

there is a charged capacitor across the output but the voltage on C1,24 has collapsed.

D2 prevents the ADJ pin from rising above the OUT pin (due to the charge on C2) if

the output is shorted.

Conventional diode D6 on the output allows supplies to be paralleled for redundancy.

The +8V Supply.

Max current rating 1.25 Amps. This supply is primarily intended for powering console

internal computers; it will be regulated down to +5V inside the console.

The AC input is fused by F4 and fullwave rectified by BR4. The unregulated DC is

about +15V on nominal mains. The LM317T regulator maintains a fixed 1.25V

between its ADJ and OUT pins, so fixed voltage-divider R68,69 gives an output of

approx 8.4 V. C23 reduces output ripple from 1 mV to approx 180 uV at full load.

Two protection diodes are included. D9 protects the regulator from reverse voltage if

there is a charged capacitor across the output but the voltage on C20,21 has collapsed.

D10 prevents the ADJ pin from rising above the OUT pin (due to the charge on C23)

if the output is shorted.

Conventional diode D11 on the output allows supplies to be paralleled for redundancy.

Mains Voltage Select PCB. SC3817

This PCB (SC3817) carries the inrush suppressor and two DPCO switches that select

the transformer primary connections to suit the incoming mains voltage.

The first switch A selects between EUROPE and USA/JAPAN settings. The second

switch B selects high and low variations on this:

Fan Control PCB. SC4032.

Thermostatic fan control was fitted to the CPS2000 from February 1999. The

controller is a separate PCB (SC4032) mounted on the front heatsink bracket, with a

thermal sensor pressed against the top surface of the heatsink.

The CPS2000 fan control system adapts the fan speed to the power drawn. This gives

asubstantial reduction in fan noise under almost all circumstances;theexception being

10% high mains and maximum current drawn, which naturally sets the fan to full

speed. The PCB (with associated mounting bracket) may be retrofitted to existing

CPS2000 units.

The servo circuit consists of opamp IC1-A, temperature sensor IC5, shunt regulator

IC4, and fan control devices TR7,TR10.

IC4 maintains 2.50V between its "anode" and "cathode"; this is the precise voltage

that drives the reference chain R53,55. TR8 also uses this voltage to set its emitter at

4.4V above ground; this keeps IC1’s inputs within their common-mode range. Thus

both ends of the voltage divider R53-R55 are fixed at defined voltages.

LM35DZ temperature sensor IC5 outputs 10mV per degreeC above freezing point (0

degC) and applies it to IC1-A non-inverting input. The desired heatsink temperature

is set at the junction of R53,55, which sits at +5.0V approx. This is 600mV above the

+4.4V rail, and so represents 60 degC.

R52,57 set the servo loop gain. This is designed to be safely below the level at which

slow thermal oscillations would occur. R56,D19 increase the loop gain when IC1-A

output is below 4V. This prevents thefan sitting for long periods in anot-quite-running

state where it consumes current but does not rotate. The voltage range 1-4V where

this occurs is thus skipped over quickly.

The fan is driven through feedback amplifier TR7,10, which has a voltage gain of 1.3

times. This allows the fan to be driven over its full operating voltage range despite the

output saturation limits of IC1-A. This gives improved cooling at high temperatures

and mains voltages.

The CPS2000 thermal shutdown system is quite separate and has no connection with

this PCB.

FAULTFINDING NOTES.

SAFETY: These safety notes are directed to those

testing and repairing this power supply. Legal

requirements mean that we must not encourage

untrained personnel to take the lid off.

+/- 17V RAILS.

1) A convenient position for attaching a test meter to 0V is the top leg of bleeder

resistor R9 (top leg of R47 on RH PCB) Remember these resistors run hot.

2) If one side of the +/-17V supply is not working, the mutual shutdown system will

close down both sides of the supply. This makes faultfinding difficult as it is often not

obvious which side has failed. The mutual shutdown can be disabled by putting on

jumpers JMP1 & JMP3 on PCBs at Issue 6 and above.

IT IS ESSENTIAL THAT THESE JUMPERS ARE

REMOVED AFTER SERVICING IS COMPLETED!

FAILURE TO DO THIS MAY CAUSE SEVERE CONSOLE

DAMAGE IF ONLY ONE 17V RAIL SHUTS DOWN.

3) If the wireform connecting the two PCBs is disconnected, the mutual shutdown

will close down both sides of the supply. The Headroom Alarm dots will also show

on the DPM as an active low from the RH PCB is required to suppress them, and this

is now missing.

4) If there is no power to the 723 IC (eg if R11 or R48 is open-circuit) the output will

remain low, but no damage occurs.

5) It is possible to swop over the two 2-pin connections on the LH PCB in error. The

fan will not run, but no circuit damage occurs.

+48V SUPPLY.

1) If TR17 fails short-circuit, the regulator will appear to work, but since all voltage

is dropped across the TL783 regulator, this will overheat and shut down at high

currents. The TL783 should not be damaged if this is the only fault present.

2) If zener DZ5 fails short-circuit, the regulator will not turn on, and there will be

only 300 mV approx at the output.

3) As usual, the unregulated supply to the +48V regulator can reach +90V, and should

be treated with some respect.

+8V SUPPLY.

1) This is a completely standard IC regulator circuit. The regulator REG3 is the only

part that is likely to fail.

2) This supply contains mains voltages on the voltage select PCB, the mains switch,

etc, and the usual precautions must be taken.

3) The main reservoir capacitors have a capacity of one tenth of a Farad, and are

charged to +26V.

THIS IS DANGEROUS.

The danger lies not in the voltage, but in the enormous currents that will flow if the

capacitor terminals are shorted. A small screwdriver will simply disappear in a violent

explosion. The main bodily danger is from metal watchstraps, etc. Serious burns are

very likely if these contact the capacitor.

For safety reasons, the reservoir capacitors are discharged at switchoff by bleeder

resistors R9 and R47; this takes about 30 seconds. Red warning LEDs on the PCB are

ON when the capacitors are charged.

Fuse Replacement

The 32A fuses mounted on either side of the transformer must be replaced with

identical parts only. Soundcraft part number ZD8900.

F1, located on the voltage selector PCB, must be replaced with an identical part.

Soundcraft part number ZD8112.

CPS2000 Fan Control & PCB SC4032

Technical Description

The later models of the CPS2000 are fitted with a fan control servo system that adapts the fan

speed to the power drawn. This gives a substantial reduction in fan noise under almost all

circumstances; the exception being 10% high mains and maximum current drawn, which

naturally sets the fan to full speed. The PCB (with associated mounting bracket) may be

retrofitted to existing CPS2000 units.

The servo circuit consists of opamp IC1-A, temperature sensor IC5, shunt regulator IC4, and

fan control devices TR7,TR10. IC4 maintains 2.50V between its "anode" and "cathode"; this is

the precise voltage that drives the reference chain R53,55. TR8 also uses this voltage to set its

emitter at 4.4V above ground; this keeps IC1’s inputs within their common-mode range. Thus

both ends of the voltage divider R53-R55 are fixed at defined voltages. LM35DZ temperature

sensor IC5 outputs 10mV per degreeC above freezing point (0 degC) and applies it to IC1-A

non-inverting input. The desired heatsink temperature is set at the junction of R53,55, which

sits at +5.0V approx. This is 600mV above the +4.4V rail, and so represents 60 degC. R52,57

set the servo loop gain. This is designed to be safely below the level at which slow thermal

oscillations would occur. R56,D19 increase the loop gain when IC1-A output is below 4V. This

prevents the fan sitting for long periods in a not-quite-running state where it consumes current

but does not rotate.

The voltage range 1-4V where this occurs is thus skipped over quickly. The fan is driven through

feedback amplifier TR7,10, which has a voltage gain of 1.3 times. This allows the fan to be

driven over its full operating voltage range despite the output saturation limits of IC1-A. This

gives improved cooling at high temperatures and mains voltages. The CPS2000 thermal

shutdown system is quite separate and has no connection with this PCB.
