13. ping transient voltages to safe levels The filter works to prevent noise from fluorescent lights certain dimmers radio transmitters and similar sources of electronic pollu tion from contaminating the AC line and from there leaking into sensitive audio video or computer circuits What sets the Furman Pro Series apart from other conditioners is the quantity quality and configuration of its suppression devices These include MOV s gas discharge tubes fast blow fuses and high voltage inductors and capacitors This unique combination can safely absorb and dissipate large spikes from nearby light ning strikes and other sources up to 11 000 amps across any wiring mode hot neutral hot ground or neutral ground as well as highly attenuate audible high frequency noise Precise high inrush magnetic circuit breakers avoid the false trip ping often encountered with large reactive loads like power amps The PM PRO front panel provides a three color 20 LED line voltage meter a true RMS reading 10 LED AC ammeter and three status LEDs to indicate abnor mal power conditions The PM PRO will even keep itself from turning on or shut down under extreme conditions if the voltage is below 80 volts or above 140 volts below 160 volts or above 280 volts for PM PRO E The front panel also provides an unswitched outlet clean filtered power is provided at the unswitched outlet too and a 20 amp 16 amp for PM PRO E magnetic circuit breaker rated
14. tage regulator Effects of Lightning Lightning is a natural phenomenon of overwhelming force that represents the most difficult circumstance faced by a power protection product The degree of protection a PM PRO can offer depends on the intensity of the strike If lightning strikes a distant power line and causes a relatively small disturbance to reach your location the spike suppressors in the PM PRO will absorb the excess voltage in visibly and harmlessly However if lightning strikes the actual building where the PM PRO is installed or somewhere very nearby some damage may be unavoid able due to the extremely high voltage and current present If this does occur most likely damage will be limited to the PM PRO itself and will affect only certain spike suppression components called varistors or MOV s In this suicide mode the PM PRO may sustain minor damage but generally will protect all equipment plugged into it from much more serious and costly damage as long as that equipment is properly grounded Proper grounding requires the use of three prong AC cords and that the building s outlets are actually grounded to earth as specified by the National Electric Code Any PM PRO known to have taken a direct lightning hit should be checked by a qualified technician or the Furman factory to determine whether the MOV s need replacement If the PROTECTION OK indicator is not lit there is definitely some damage Some spike suppression capabili
