The automatic recovery over- 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 safety of electrical equipment and people. The device will resupply after 1 minute, when the power returns to normal.
