The Computer Power Filter has a Lifetime Warranty & $80,000 Connected Equipment Warranty

Designed and Engineered in Australia by PowerGuard Protective Electronics, PowerGuard Computer Power Filter PGCP3906 is an absolute state of the art Telecommunications Power Protective device, specifically designed for serious professional users of PC’s and Notebooks with modems and high quality multi function centres.

The Computer Power Filter uses a combination of conventional MOV, Ferrite Core and Capacitance technology for AC Mains and features DC protection for conventional phone line and/or ADSL/Ethernet protection.

PowerGuard Computer Power Filter PGCP3906’s AC filter is designed for clamping and energy dissipation, but is arranged in a cascade, multi-stage circuit design – the benefit is that rather than totally block all the excess energy and risk causing a back EMF, that could damage neighbouring unprotected equipment, the protection is designed to capture, absorb and dissipate the excess energy or transient interference. Residual interference is captured by each successive stage; the cascade circuit design captures any graduated overflow at each successive stage of the filter providing cleaner power.

Designed to protect sensitive electronic equipment from potentially damaging and dangerous high voltage spikes, RFI, EMI and transient voltage on the AC Mains electrical supply, by capturing and diverting electrical disturbances within the scope of the protection that commonly cause breakdown, poor performance, data loss and data corruption and long term cumulative damage or total destruction of unprotected connected equipment.
