Function:
1 In standard modular construction, the product installs through guide rails and requires no additional auxiliary power supply.
2. The overshortage voltage protection has two sets of normal open and close contacts and five indicators to indicate various operating conditions.
3 The overvoltage and low voltage values are individually adjustable and the working time is adjustable.
4 Voltage monitoring relay can realize real-time monitoring of three phase overvoltage, undervoltage and phase shifting, phase loss, voltage imbalance, and neutral disconnect failure.
5 This product can be used with electric motors, fans, water pumps, cranes, driving, lifts, elevators, machine tools, central conditioners, freezing equipment, industrial control systems and more.
