Overvoltage DC Voltage Monitoring Relay DC battery undervoltage protective relay
The monitoring relay is a commonly used electromagnetic relay. The voltage monitoring relay is used for voltage protection and control of the electric drive system. The coil is connected in parallel to the main circuit to sense the line voltage of the main circuit; the contacts are connected to the control circuit and are the actuators. According to the size of the pull-in voltage, the voltage relay can be divided into over-voltage relay and under-voltage relay.
Monitoring relay is self-contained detection circuit, active control
