Voltage Protector is also called as Power Guard, Safeguard or Automatic Voltage Switcher, which is designed to protect all the voltage sensitive appliances like refrigerators, air conditioners, etc. It can automatically disconnect the mains power once the voltage is out of the normal range, preventing the appliances being damaged due to over voltage or under voltage. Once the mains voltage backs to normal range, it will automatically reconnect the mains power.
