Automatic Voltage Switcher

The AVS principle

For complete protection simply plug the Automatic Voltage Switcher into the mains and plug in your appliances. When the mains power supply fluctuates outside pre-set tolerances (nominally 190V and 260V) the power to your equipment is disconnected. The AVS monitors the voltage for a short period to ensure the power has stabilized before re-connecting. In addition, the stat-up delay provides protection against power-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 events which are very common. They are generated by lightning and nearby switching off and on of other equipment such as vacuum cleaners, Pumps, motors, televisions, elevators etc.
