The AVP is an Automatic Voltage Protector rated at 30/40/60/80/100 Amps (AVP30/AVP40/AVP60/AVP80/AVP100). The AVP will switch off the equipment connected to it if the mains power goes outside preset acceptable limits and will re-connect automatically - when the mains power returns to normal. Re-connection takes place after a delay ('the start-updelay') to ensure stability of the mains.

In addition, the start-up delay provides protection against power-back surges commonly experienced after resumptionof power in a power cut situation.

Surge and spike protection is also incorporated to ensure protection against these commonly occurring events.
