◎ Overview

The OBD1GQR/OBD1GQZ self recovering overvoltage and undervoltage protector is a new generation of home appliance protection device developed by our company based on the current power supply situation.It can provide protection in case of abnormal voltage.When the mains voltage exceeds or fall below the operating voltage value of the protector,the protector can quickly and reliably cutoff the load power supply to protect electrical appliances and personal safety. When the mains voltage returns to normal,the protector automatically  connects to the power supply,restoring power and achieving fully automatic control It has the characteristics of simple and convenient use, stable and reliable performance.The product has a compact structure,beautiful appearance,and is installed in parallel with DZ47S.The  product complies with the JB/T12762 standard for self recovering overvoltage and undervoltage protectors.

Single phase overvoltage and undervoltage

1.Red light flashing,overvoltage automatically disconnected;

2.The red lightflashes slowly,and the undervoltage automatically disconnects;

3.The green light is always on,and the normal working voltage is automatically connected;

Three phase fourwire overvoltage and undervoltage

1.Red light flashing,overvoltage automatically disconnected;

2.The red light flashes slowly,and the undervoltageautomatically disconnects;

3.The green light is always on,and the normal working voltage is automaticallyconnected;

4 .Red light always on,phase missing(4P product);

5.The main working characteristic of 4P products is the phase line voltage(L-N);
