      30A/50A

      TBB AVS is an Automatic Voltage Switcher built-in with a microprocessor. The AVS will switch off the equipment connected to it if the grid voltage goes beyond threshold limits and will re-connect automatically when the mains power returns to normal. Re-connection takes place after a time delay to ensure the stability of the mains. In addition, the start-up delay provides protection against power-back surges which are commonly experienced after the recovery of power. Surge and spike protection are also incorporated to ensure protection against these commonly occurring events.
