DC Voltage Controlled 3 Phase Protection Relay 12V 24V 36V 48V High Low Voltage Monitor

For all electrical equipment, there is a rated voltage, but in practice, it is not guaranteed to work at rated voltage, it is a range around the rated voltage, generally required to be ±15%. In order to protect the electrical equipment and process quality, if it is higher than +15%, it is "overvoltage" and the protection action cuts off the power supply.

Principle of overvoltage protector
The simplest is to connect a "varistor" in parallel with the power supply line. When the voltage is overvoltage, the varistor breaks down, so that the front end is open or safe, and the back end is out of overvoltage. Disadvantage: varistor overvoltage Need to be replaced after breakdown.
