      Automatic Voltage Switch

      AVS

      30A/50A

      TBB AVS (Automatic Voltage Switch) is equipped with a microprocessor to manage equipment protection against voltage fluctuations. It disconnects connected equipment when the grid voltage exceeds predefined threshold limits and automatically reconnects once mains power returns to normal, following a time delay to ensure stability. This delay also safeguards against power-back surges often seen after power recovery. Additionally, the TBB AVS includes surge and spike protection to defend against these common electrical disturbances.
