Furman PowerPort

PowerPorts comprise the building blocks of Furman's versatile new high performance power conditioning and distribution system, intended for medium size to the largest audio, video, and multimedia installations.  Such a system can grow to any size, yet be conveniently controlled from any location.  An individual PowerPort provides control, timing, monitoring, and power conditioning capability for a single equipment site. All critical circuit functions are governed by an internal microprocessor.

PowerPorts offer the same renowned RFI/EMI and spike/surge protection as Furman's top-of-the-line PRO Series rackmount power conditioners.  A PowerPort can safely absorb up to a whopping 11,000 amperes of spike/surge current in any mode (hot-neutral, neutral-ground, or hot-ground), using a unique array of protection devices including MOV's, gas discharge tubes, high voltage inductors and capacitors, and fast-blow fuses.  It also provides over 60 dB of common-mode attenuation in the 1-200 MHz RF band.

An additional feature, Extreme Voltage Shutdown, fights a hazard particularly common in the entertainment industry: wiring faults -- for example, accidental connection to 220V.  It senses voltages that are so high or low that operation would be impossible (under 80V or over 140V) and shuts the power down before damage can occur. An "Extreme Voltage" LED blinks a red alert when an abnormal voltage causes shutdown.  Other status indicators ("Protection OK" and "Ground OK") monitor the integrity of the protection devices and grounding, and report if the protection is compromised.  A "Mains OK" LED glows steady for normal input voltage and blinks a warning for marginal but not extreme voltages (80-90V or 130-140V).

As a power sequencer, PowerPort has independent turn-on and turn-off delays, with simple daisy chaining for remote switching of single or an unlimited number of multiple units.  Control wiring can be up to five miles in length without performance degradation, based on using 24 AWG.  The PowerPort has two modes of operation: maintained and momentary.  These terms refer to the type of switch that is attached to the remote terminals, and determine the functionality of the unit.  The mode may be easily changed by moving a suitcase jumper on the circuit board.
