Voltage and current display relay is a microprocessor-based voltage monitoring device for single-phase AC networks to protect electrical equipment from surge voltage.The device analyzes the main voltage and displays its current value on a digital indicator. Load is switched by electromagnetic relay.The user can set the current voltage value and delay time through the button.
The value is stored in non-volatile memory.Aluminum wires and copper wires can be used for connection.
Voltage and current display relay used in administrative,industrial and residential buildings and has the function of protecting single-phase lines:
Undervoltage protection;
Overvoltage protection;
Working under voltmeter mode.
