The Extreme Notebook Power Filter has a Lifetime Warranty & $100,000 Connected Equipment Warranty

Designed and Engineered in Australia by PowerGuard Protective Electronics, PowerGuard Extreme Notebook Power Filter PGXN3702 is stand out proven protection with innovative patented technology. Designed to provide Over Voltage, Surge and Under Voltage (sag, brownout) protection at the AC mains and incorporating DC telecommunications protection; PowerGuard Extreme Notebook Protector is a totally unique micro-processor controlled protective device, factory set to provide a safe operating window for the direct connected equipment. PowerGuard is fully automatic, designed for a 230/240 Volt 50Hz AC Mains electrical supply.

As soon as the AC voltage supply moves outside the safe operating window (190 Volts Low to 265 Volts High/230V AC 50Hz) PowerGuard Extreme Notebook Power Filter immediately switches OFF power to the protected equipment and remains OFF until a safe mains supply voltage is detected, giving sensitive equipment proper protection when needed and whenever isolation occurs, providing the connected equipment with a vital minimum time delay before power is restored (e.g. prevents hard drive lock-up in computer equipment).The PowerGuard Extreme Notebook Power Filter is not earth dependent or amperage reacting, therefore events such as loss of a neutral link and the resultant continuous high voltage is rapidly detected and protection is activated, before damaging your vital electrical or electronic equipment. Reliable protection 24/7.


>Ultra compact dual protected AC outlets for exceptional travel connectivity.
>Dual protection - AC mains and phone DC LINE.
>Over voltage and surge protection.
>Under voltage protection.
>Slow average fluctuation protection.
>Time delay auto reset (on safe power)
