Furman PMPROII Series II 20 Amp Power Conditioner

FURMAN PMPROII Details ^top

The latest generation of Furman’s legendary 20 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 PL-PRO II, PL-PRO D II and PM-PRO II power conditioners, 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 world’s 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 “sacrifi ce” 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 sacrifi ced parts, no service calls, no down time.

Unique to Furman’s SMP is its unparalleled clamping voltage. Unlike some series mode suppressors, Furman’s maintenance free feature is not at the expense of potential equipment failure! 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 whether multiple pole fi 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 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.

FEATURES
The PL -PRO II and PL-PRO D II feature LED rack lights which produce virtually no heat and provide an extremely long life span. A dimmer control for the rack lights allows the user to adjust the level of illumination or simply switch the lights off.

Additionally, all units include 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. A front panel mounted master power switch is protected by a hinged cover, preventing accidental disconnection of AC power to the unit’s outlets. The front-panel circuit breaker - power switch can be quickly and easily reset should the unit be overloaded. Furman’s Series II Pro units also feature a 10 foot, 12 gauge heavy-duty power cable.

ADDITIONAL PM-PRO SERIES II FEATURES:
Front panel digital meter displays incoming AC line voltage with laboratory
accuracy (+/- 1.5 VAC)
Additional front panel true RMS digital meter displays AC current draw with laboratory accuracy regardless of load reactance, inductance or resistance (+/- 0.1 amp)
