SERIES II 15 AMP PowER CondItIonERS
I N T R O D U C T I O N
Thank you for purchasing a Furman Series II
Power Conditioner, and congratulations on
your choice. The Series II power conditioners
feature Furman’s revolutionary Series Multi-
Stage Protection Plus (SMP+) circuit, as well
as our exclusive Linear Filtering Technology
(LiFT). Together, these technologies comprise
what is, without question, the world’s most
advanced and comprehensive transient
voltage surge suppressor / conditioner.
SMP+ (Series Multi-Stage Protection Plus)
Furman’s SMP+ surge suppression virtually
eliminates service calls. Traditional surge
suppression circuits “sacrice” 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.
Unique to Furman’s SMP+ is its unparalleled
clamping voltage. While other designs offer
clamping voltages that are well above 330 Vpk,
Furman’s SMP+ clamps at 188 Vpk, (133 VAC
RMS) even when tested with multiple 6000 Vpk
- 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 240 VAC, by shutting off the incoming power
until the over voltage condition is corrected.
[For E versions: Furman’s SMP+ clamps at 376
VpK, (266 VAC RMS.)]
LiFT (Linear Filtering Technology)
Unfortunately, traditional AC lter - conditioners
have been designed for unrealistic laboratory
conditions. Prior technologies, whether
multiple pole lter 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 ltering and no leakage to
ground.
