I understand the basics but how does the PowerGuard Protect?
The PowerGuard features a patented microprocessor controlled comparator circuit, which isolates power immediately it detects voltage outside a pre-set safe window (190VAC - 265VAC) and automatically restores power once power has returned within these safe levels. Uniquely the PowerGuard is not earth or amperage dependent making it ideal protection against Ground Surge from Lightning in lightning prone areas.

PowerGuard is recommended for protection of all appliances and equipment that are powered from AC mains power, reducing the risk of damage from Under Voltage (Power Sags), Surges, Over Voltage and Slow Average Fluctuations or Brown Outs.

PowerGuard also features a timer controlled delay circuit to ensure that power remains isolated for a minimum of three seconds, reducing the risk of Hard Drive Lockup in computers due to rapid "Off and On" switching of power.
