DESCRIPTION
The most widely recognized and trusted name in AC power
conditioning is proud to introduce the PS-PRO II power
conditioner / sequencer, featuring Furman’s revolutionary
SMP+ technology. Furman’s Series Multi-Stage Protection
Plus (SMP+) circuit features our exclusive Linear Filtering
Technology (LiFT) and Extreme Voltage Shutdown (E.V.S.).
Together, these technologies comprise what is, without question,
the world’s most advanced and comprehensive transient voltage
surge suppressor.
Additionally, the PS-PRO II Power Conditioner/Sequencer is
capable of powering up a rack full of equipment in a 3-step
delayed sequence. The sequence is reversed for power-down. The
sequence can be initiated with either momentary or maintained
switches, locally or remotely. A duplex outlet is provided for each
delay step. A front panel screwdriver adjustment sets the delay
time for the PS-PRO II. The PS-PRO II also features a locking
switch with a removable key for maximum security. One or more
Furman PS-PRO II’s may be installed in remote locations and
operated via low-voltage wiring. The PS-PRO II includes a rear
mounted BNC jack which accepts any standard (12VAC, 0.5A)
gooseneck lamp for rear rack illumination, as well as a front panel
switch which controls the gooseneck’s operation.
PS-REL Relay Accessory
Allows a PS-PRO II to be turned on by sensing AC at a
preamp’s switched outlet; also allows daisy-chaining for
6 or more delayed outlet groups.
Export Models
Models PS-PRO E II: “E” suffix versions are for use in countries
with 220/240 volt AC lines. Furman Power Sequencers use
internationally accepted IEC-320 connectors.

Series Multi-Stage Protection Plus (SMP+)
SMP+ is Furman’s proprietary surge suppression and noise
filtration system. Designed over a period of two years by our
California based engineering team, SMP+ is composed of
three separate and distinct technologies which work together
in a precisely tuned circuit to filter or “clean” the incoming
power and to protect connected equipment from potentially
damaging AC events. These technologies are Linear Filtering,
Series Multi-Stage Protection, and Extreme Voltage Shutdown.
Linear Filtering Technology (LiFT):
Unfortunately, traditional AC filter conditioners have been
designed for unrealistic laboratory conditions. Prior technologies
could actually harm audio and video performance more than
they help, due to the resonant peaking of their antiquated, nonlinear
designs. Under certain conditions, these designs can
actually add more than 10 dB of noise to the incoming AC line!
Worse still, lost digital data, the need to re-boot digital pre-sets, or
destroyed digital converters are frequently caused by excessive
voltage spikes and AC noise contaminating the equipment ground.
Furman’s LiFT takes another approach, ensuring optimal
performance through linear filtering and no leakage to ground.
Series Multi-Stage Protection (SMP):
Traditional surge suppression relies on circuits that “sacrifice”
themselves when exposed to multiple transient voltage spikes,
requiring the dismantling of your system and repair of your surge
suppressor. With Furman’s SMP+, however, damaging transient
voltages are safely absorbed, clamped and dissipated. No sacrificed
parts, no service calls, no downtime. Also unique to Furman’s
SMP+ is its unparalleled clamping voltage. While other designs
offer clamping voltages that are well above 300Vpk, Furman’s
SMP+ clamps at 188Vpk, 133 VAC RMS, even when tested with
multiple 6000Vpk - 3000 amp surges! This unprecedented level
of protection is only available with Furman’s SMP+ technology.
Extreme Voltage Shutdown (E.V.S.):
When voltage rises to extreme levels because of a lost neutral
line or an accidental connection to 208 or 240 VAC, Furman’s
Extreme Voltage Shutdown kicks in, automatically powering down
all equipment quickly and safely in order to prevent damage
from occurring. An indicator LED will then illuminate, alerting
you to the situation until the over voltage condition is corrected.
