additionally, the Power factor Pro is the most
comprehensive power conditioner ever created
for the serious musician. furman’s series
Multi-stage Protection Plus (sMP+) guards
your equipment from voltage spikes that can
damage your amplifier or other connected
equipment.
furman’s sMP+ features unparalleled
clamping voltage. While other designs offer
clamping voltages that are well above 330Vpk,
furman’s sMP+ clamps at 188Vpk (133 VaC
rMs) even when tested with multiple 6000Vpk
- 3000 amp surges! and, our pro level over-
voltage auto shutdown circuit assures you will
never see your prized amplifier go up in flames
due to a sustained voltage overload.

instructions for future reference.
the Pf-Pro has a generous 12 amp r.M.s.
capacity, a convenient 20 segment aC
voltmeter, a detachable-locking aC cord,
and (4) aC outlets, all contained in a small
convenient, floor standing package. The PF-
Pro r has the same features except its cord
is not detachable and it has (8) rear outlets
and (1) front panel outlet. it also features
a BnC connector on the rear panel to allow
attachment of any standard gooseneck lamp
(such as furman’s model Gn-i or Gn-led) to
illuminate the rear of your rack.
2. Your Power factor Pro unit should not be
used near water – for example, near a bathtub,
washbowl, kitchen sink, laundry tub, in a wet
basement, near a swimming pool, etc.
3. do not place your Power factor Pro unit
near heat sources such as radiators, heat
registers, stoves, or other appliances that
produce heat.
4. the Power factor Pro should only be
connected to a 120 VaC, 60Hz, 15 amp (“e”
version - 220 VaC, 10 amp) grounded electrical
outlet. do not defeat the ground or change
polarization of the power plug.
5. Pay particular attention to the condition of
the cords and cables at the plugs. to prevent
risk of fire or injury, damaged cords and cables
should be replaced immediately.

6. Clean your Power factor Pro unit with
a damp cloth only. do not use solvents or
abrasive cleaners. never pour liquid on or into
the unit.
the Power factor Pro, offers a 20 segment
led bar-graph meter that displays incoming
voltage between 90 and 128 volts in 2-volt
increments. the normal range voltages are
indicated in green, with moderately and
extremely high or low voltages in yellow and
red respectively. the voltmeter’s accuracy
is ±2 volts. it can easily be recalibrated, if
necessary.
7. Your Power factor Pro unit should be
serviced by qualified service personnel when:
• the power supply cord or the plug has been
frayed or cut.
• Objects have fallen or liquid has spilled into
the unit.
• the unit has been exposed to rain or other
moisture.
• the unit does not appear to operate normally.
• the “Protection oK” indicator is not lit.
• the unit has been dropped, or the enclosure
has been seriously damaged.
the Pf-Pro r features a rear rack BnC
socket which will accept any 12 VaC (0.5a)
gooseneck lamp assembly, (such as the
furman Gn-led or Gn-i). simply slide the
BnC plug over the socket and rotate clockwise
until the connector snaps into the locked
position. the rear rack lamp can be powered
on or off with the rear light power switch
located on the far left of the front panel.
8. Your Power factor Pro unit requires that a
safety ground be present for proper operation.
Any attempt to operate the unit without
a safety ground is considered improper
operation and could invalidate the warranty.
o P e r at i o n
multi-Segment leD Voltmeter:
this three-color, 20-led bargraph is an
accurate, self checking aC voltmeter that
continually measures input voltages. the
meter reads from 90 to 128 volts in 2 volt
steps (Power factor Pro e: 180 to 256 volts,
in 4 volt steps). the normal range voltages
are indicated in green, with moderate and
extremely high or low voltages in yellow and
red respectively. the voltmeter provides three
special flashing patterns to indicate abnormal
conditions.
9. do not attempt to service your Power factor
Pro unit beyond what is described in this
manual. all other servicing should be referred
to qualified service personnel.
f e a t u r e s
the Power factor Pro has a master switch for
the rear outlets that glows red when the power
is on. The circuit breaker is located adjacent to
the power switch for the Pf-Pro and on the rear
panel for the Pf-Pro r. it can be quickly and
easily reset should the unit be overloaded. the
Pf-Pro also features a detachable 10 foot, 14
gauge heavy-duty power cable.
(1) on initial turn on, the voltmeter will
scan for smart chip integrity.
(2) if only the single leftmost (beneath
the 90V mark) LED flashes, the input
voltage is marginally low.

(3) if all of the leds on the voltmeter
flash, the input voltage is marginally
high. Power to the Power factor
Pro’s outlets will remain on unless the
incoming voltage rises above the
extreme Voltage shutdown (eVs)
cut-off voltage (135 - 140 volts).
to the “on” position.
extreme Voltage Shutdown (eVS) Indicator:
this led is normally off. it monitors a hazard
unfortunately common in the entertainment
industry: wiring faults – for example, accidental
connection to 220VaC where 120VaC is
expected, or an open neutral from a 208 or
240VaC feed. the Power factor Pro’s sMP+
circuit senses voltages that are so high that
operation would be impossible and shuts the
power down before damage can occur. upon
initially applying power to these units, the
extreme Voltage indicator led will be lit if the
input voltage is above the extreme voltage
cutoff, and power will not be applied to the
unit’s outlets. if the unit has been operating
with an acceptable input voltage and then that
voltage goes above 135V, it will shut off power
to the outlet and the extreme Voltage led will
light.
the Power factor Pro’s voltmeter has a basic
accuracy of plus or minus two volts, and
extreme cold or heat may cause an additional
one volt of error (four volts and two volts for
Power factor Pro e).
NOTE: although the Power factor correction
will more than compensate for peak current
demands, the Power factor Pro does not
compensate for sustained high or low line
voltage. if you derive power from generators,
travel internationally, or are in an area prone
to extreme brownouts, you may benefit from
the use of one of furman’s aC line Voltage
regulators.
note: if the mains power is above the high
cutoff voltage and has caused the unit to
remove power from its outlets, it cannot restore
power without the operator manually turning
the unit off, then on again. avoid turning the
unit back on without checking the source of the
on/off rocker Switch:
this 15 amp capacity power switch is
specifically designed to stand up to the
enormous high inrush current demands placed
by many instrument amplifiers. Additionally, the problem first, and perhaps changing the AC
semi-transparent rocker lights when switched source.

Importantnote:
The Power Factor Pro must be the first AC power component connected to the AC mains!
regulators such as the furman ar-1215 or uPs systems such as the sB-1000 must be
connected to the Power factor Pro’s output. this is due to the fact that the Pf-Pro’s current
reservoir may hinder the performance of a regulator, and worst case may cause damage in
extreme power environments.
as long as the Power factor Pro is connected prior to the regulator or uPs both components
may be used.
