Automatic Voltage Switcher - AVS30

The AVS is an Automatic Voltage Switcher rated at 30 Amps(AVS30). The AVS will switch off the equipment connected toit 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-up delay’) to ensure stability of the mains.

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

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

Function

This new version of the AVS has a built-in micro-processor that has added advanced features to the product. These include

Five voltage indicators

• The power supply is good and the load is connected.
• The AVS has detected that the mains voltage is too high and therefore dangerous to your equipment. The AVS has disconnected the power supply.
• Power supply has returned to normal (after an over-voltage condition - see above). The AVS is waiting before the power supply is restored to your equipment.
• Power supply has returned to normal (after an under-voltage condition - see below). The AVS is waiting before the power supply is restored to your equipment.
• The AVS has detected low voltage condition and has disconnected the power to your equipment to protect against it.
