Auto over/under voltage protector

The automatic over/under voltage protector complies with modular design standards. The circuit boards of products adopt imported 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 safely of electrical equipment and persons. When the voltage returns to normal indic ators on the panel show very intuitive work states, first indicator (red) is shinning to show that product is in the state of over voltage, power can break au tomatically, and the second indicator (green) is shinning when power is normal supply, the third indicator (red ) is shinning when under voltage state, when the fourth indicator (yellow) is shinning, power of product re-supply for 2-3 minutes
