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. It's 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 safely 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.

The red indicator display, when the power over voltage or under voltage.
