The Furman P-8 PRO C features Furman’s venerable Series Multi-Stage Protection (SMP) circuit as well as our exclusive Linear Filtering Technology (LiFT). Together, these technologies comprise what is, without question, the worlds 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 “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 down time.
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. Additionally, Furman’s trusted over-voltage circuitry protects against all too frequent open neutral wiring, or accidental connections to 208 or 240 VAC. Furman’s SMP+ with over voltage protection immediately shuts off the incoming power until the over voltage condition is corrected.
LiFT (Linear Filtering Technology)
Unfortunately, traditional AC 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, 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 reboot digital presets, 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 fi ltering and no leakage to ground.
EVS (Extreme Voltage Shutdown)
Transient spikes and ground contamination are not the only problems faced by today’s sensitive electronics. There are also sustained over voltage conditions, sometimes called extreme voltages. Many surge suppression devices will not be able to protect equipment from sustained over voltages. These conditions can occur for multiple reasons: a power pole may be damaged during a storm or accident; or, in many countries, such as USA and Canada, lost or intermittent neutral wiring of a multiple-zone system can result in a sudden connection well in excess of 208 volts AC. Many surge suppression devices are not equipped to handle these kinds of conditions. Without proper protection, the end result is destroyed equipment or, at best, a destroyed surge suppression system.
Furman’s EVS constantly monitors incoming voltage, and once any overvoltage condition over 137 volts AC is detected, a relay opens which immediately shuts down the unit and all connected equipment. An indicator light informs the user there is a problem, and once the condition has been corrected, the unit may be reset and will operate normally.
