Digital Voltage Meter
SUMMARY - Furman pm-8ii
Rack Mount Power Conditioner
The latest generation
of Furman’s legendary 15 amp power conditioners, featuring Furman’s
exclusive Series Mode Protection (SMP) with Linear Filtering Technology (LiFT).
DESCRIPTION
The most widely recognized and trusted name in AC power conditioning, is
proud to introduce the PM-8 II Power conditioner, featuring Furman’s
revolutionary SMP technology. Furman’s Series Mode Protection (SMP) circuit
also features our exclusive Linear Filter Technology (LiFT). Together; these
technologies comprise, what is without question, the worlds most advanced
and comprehensive transient voltage surge suppressor.
SMP (Series Mode Protection) Furman’s
maintenance-free SMP surge suppression virtually eliminates service calls.
Traditional surge suppression circuits “sacrifice” themselves when exposed
to multiple transient voltage spikes, requiring the dismantling of your
system, and repair of your surge suppressor. Not so with SMP. With Furman’s
SMP, damaging transient voltages are safely absorbed, clamped and
dissipated. No sacrificed parts, no service calls, no down time. Unique to
Furman’s SMP is its unparalleled clamping voltage (even when tested beyond
the grueling specifications of - USA/CIDA’s A-1-1 test). Unlike some Series
Mode Suppressors, Furman’s maintenance free feature is NOT at the expense of
safety! While other designs offer clamping voltages that are well above
300VAC peak, (far beyond long accepted professional standards), Furman’s SMP
clamps at 188VAC peak, 133 VAC RMS even when tested with multiple 6000VAC -
3000 Amp surges! This unprecedented level of protection is only available
with Furman’s SMP technology. Additionally, Furman’s trusted over-voltage
circuitry protects against all too frequent accidental connections to 208 or
240VAC, by shutting off the incoming power until the over voltage condition
is corrected.
LiFT (Linear Filtering Technology)
Unfortunately, traditional AC filter - Conditioners have been designed for
unrealistic laboratory conditions. Prior technologies whether multiple pole
filter or conventional series mode, could actually harm audio and video
performance more than they help, due to the resonant peaking of their
antiquated, non-linear 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 SMP with LiFT takes
another approach, ensuring optimal performance through linear filtering and
no leakage to ground.
