VL-VPR-103 Over/Under-Voltage Protector, 40A

The over/under-voltage protector continuously monitors the supply and disconnects the load when the voltage moves outside the safe range, reconnecting once power returns to normal — protecting equipment on unstable grids.

Key Features

  • Under voltage and over voltage protector.
  • The automatic recovery over voltage and under voltage protective device complies with modular design standards.
  • The circuit boards of products adopt good quality electronic components with reliable performance.
  • When the power situation is unstable.
  • Its protection function will be automatically activated.
  • Once the voltage exceeds the limited range of products, it will automatically cut off so as to protect the safety of electrical equipment and persons.
  • The device will re-supply in 1 minute, when the power returns to normal.
  • The green indicator display, when the power is normal supply.
