Section 1
Introduction
1.1 General Description
The 960PS Power Supply is used to supply power to the modules that are plugged into the
960MB/961MB motherboards.
The power supply is mounted outside of the 960CC Card Cage Module, the wall mounted Local Control
Unit enclosure, or control room cabinet. The input AC voltage is soft started to inhibit current surges when
powered up. EMI protection is also provided as part of the AC voltage protection. The power supply has
remote error sensing and short circuit/overload protection along with input and output over-voltage
protection. See Figure 1-1, the Power Supply Functional Block Diagram.
1.2 Application
The 960PS-200 & 960PS-210 Power Supply Modules are used in VICTOREEN series area monitors,
process monitors, isolators, control rooms, and safety-related display cabinets.

1.5 Installation
The 960PS-200 and 960PS-210 Power Supply Modules are supplied as part of a radiation monitoring
system (RMS) or as replacement parts for an existing RMS. When the power supplies are shipped as part
of a system, they are installed at the factory.
When a module is shipped as a replacement part, verify the integrity of the gasket, heat sink, and seal
screw fasteners (when used) prior to installation. Apply P/N 88-10 thermal coat, or equal heat transfer
compound between power supply and heat sink to ensure the thermal coupling of the installed power
supply. For operation of the 960PS-210 at 220 VAC, verify the location of the internal supply voltage
jumper E1. The part number of the required mounting hardware may be found in the system assembly
drawing section of the applicable systems manual.
1.6 Procedures, Warnings, and Cautions
The equipment described in this manual is intended to be used for the detection and measurement of
ionizing radiation. It should be used only by persons who have been trained in the proper interpretation of
its readings and the appropriate safety procedures to be followed in the presence of radiation.
Although the equipment described in this manual is designed and manufactured in compliance with all
applicable safety standards, certain hazards are inherent in the use of electronic and radiometric
equipment.
WARNINGS and CAUTIONS are presented throughout this document to alert the user to potentially
hazardous situations. A WARNING is a precautionary message preceding an operation that has the
potential to cause personal injury or death. A CAUTION is a precautionary message preceding an
operation that has the potential to cause permanent damage to the equipment and/or loss of data. Failure
to comply with WARNINGS and CAUTIONS is at the user's own risk and is sufficient cause to terminate
the warranty agreement between Fluke Biomedical and the customer.
Adequate warnings are included in this manual and on the product itself to cover hazards that may be
encountered in normal use and servicing of this equipment. No other procedures are warranted by Fluke
Biomedical. It shall be the owner's or user's responsibility to see to it that the procedures described here
are meticulously followed, and especially that WARNINGS and CAUTIONS are heeded. Failure on the
part of the owner or user in any way to follow the prescribed procedures shall absolve Fluke Biomedical
and its agents from any resulting liability.
Indicated battery and other operational tests must be performed prior to each use to assure that the
instrument is functioning properly. If applicable, failure to conduct periodic performance tests in
accordance with ANSI N323-1978 (R1983) Radiation Protection Instrumentation Test and Calibration,
paragraphs 4.6 and 5.4, and to keep records thereof in accordance with paragraph 4.5 of the same
standard, could result in erroneous readings or potential danger. ANSI N323-1978 becomes, by this
reference, a part of this operating procedure.

Operation
960PS-200 Power Supply

Section 2
Operation
2.1 960PS-200 Power Supply
The 960PS-200 supplies three different DC voltage outputs to the 960 modules through the
960MB/961MB motherboard. 115 VAC is connected to terminal strip A3, part of the front panel. The AC
line voltage is fed to a bridge rectifier circuit and rectified by diodes CR1, CR2, CR3, and CR4. A
thermistor is connected in series with the incoming AC voltage to decrease the effect of "turn-on" in-rush
current to the power supply. For all practical purposes this is a soft start device. On some models of the
power supply a current limiting resistor is used rather than a thermistor. Refer to schematic drawing
960PS-200-53
2.2 Input Filter
The rectified voltage from the bridge goes to a filter network made up of inductor L1 and a capacitor C1.
This filter removes the DC voltage line ripple resulting from the rectification process.
2.3 DC to DC Converter
The voltage is supplied to a DC to DC converter circuit. The converter has an oscillator circuit, with its
transformer and transistors, converts the DC voltage to a high frequency AC voltage. Transformer T1 has
the oscillator Q1 in the primary and as part of the secondary a feed back winding. The purpose of the
feed back winding is maintaining oscillations independent of circuit loading. There are three outputs on
T1's secondary that provide the source voltage for the power supply output voltage.
The output from T1 at pin 7 is rectified to DC by CR1 and CR2 and fed through another filter circuit. The
output goes to two zener diodes VR1 and VR2. The zener diodes regulate the voltage down to 15 V. The
15 V is supplied to the circuits in the power supply.
2.4 Voltage Regulation
One of the zener diodes, VR2, regulates the voltage that is used in the 5 V and short circuit/overload
protection circuit. Operational amplifier AR1 acts as a voltage regulator by comparing the voltage output
to a reference 5 volts. The output 5 V is fed to terminal strip A3.
An output is also fed to the -15 V and +15 V circuits. These two circuits function much the same as the +5
V. The only difference is that the +5 V circuit is the primary output circuit and it controls all the other
secondary circuits. In addition to this only the +5 V circuit has protection.

2.5 960PS-210 Power Supply
The 960PS-210 Power Supply is similar in operation to the 960PS-200, with the exception that it
incorporates an additional 24 VDC output, an input voltage sensing circuit, and a common and differential
mode choke. Refer to schematic drawing 960PS-210-53.

Maintenance
Section 3
Maintenance, Calibration and Troubleshooting
3.1 Maintenance
No periodic maintenance is required for the module. The output voltage levels, however, should be
verified periodically.
NOTE
If a maintenance question arises and cannot be
resolved by using this manual, please contact Fluke
Biomedical at 440.248.9300.
3.2 Calibration
There are no user adjustments on the main 960PS-200. Should the output voltage fall outside of the
tolerance specified, the unit must be returned to Fluke Biomedical for repair.
Adjustments to the 960PS-210 are limited to the AC Line Monitor Voltage trip point adjustment (R40),
mounted on the stand-up circuit board, and the +5 VDC output voltage adjustment (R17). Adjustments to
sealed potentiometers; R16 (FREQ.), R27 (CURR.), and R28 (OUP.) should be performed only by
factory-trained technicians. Should the output voltage fall outside of the tolerance specified, the unit must
be returned to Fluke Biomedical for repair.
3.3 Troubleshooting
WARNING
Extreme care must be used when troubleshooting a
system that has power applied. All standard
troubleshooting precautions apply.
WARNING
Once a problem has been located, remove all
power before continuing with the repair.
CAUTION
Personnel performing the following procedure must
be familiar with the operation of the monitoring
system and the location of each piece of equipment
used in the system.
