Electrical DC Voltage Monitoring Relay over and under voltage relays

 

When the motor is in normal operation, excessive reduction of the power supply voltage will cause the motor speed to drop or even stall. When the load torque is constant, the motor current will increase sharply and cause over-current. In addition, the voltage is too low will cause some electrical appliances to release, cause the control circuit to work normally, may have the accident. Therefore, it is necessary to cut off the power supply when the voltage drops to the minimum allowable value. This is undervoltage protection. Its task is mainly to prevent equipment from burning due to overload.

 

When the voltage drops, the motor runs under voltage. Since the load of the motor is not changed, the motor speed falls under the voltage and the current in the stator winding increases. Because the magnitude of current increase is not enough to make fuses and thermal relays act, both appliances will not protect. Failure to take protective measures will overheat and damage the motor over time. In addition, the under voltage will cause some electrical appliances to release, making the circuit unable to work normally. Therefore, avoid long-term operation of the motor under voltage

 

The  DVM-A is the device can protective over and under voltage for dc circuit  which can monitoring long time arrivaled several years the two LED light could Prompt the situation of cabinet or electrical cotrol system 

 

The adjustable setting with potentiometer and the delay time is from 1~10 second adjustbale
