The voltage relays are designed to monitor undervoltage, overvoltage and voltage ripple in DC network and generate an output signal when the monitored voltage and voltage ripple exceed the preset limits within the preset time
Buttons on voltage relay front panel are used to set parameter values
LED alarm and display on the front panel of voltage relay indicate actuation and operation status
Voltage relay features RS-485 interface for communication with PC and the upper level of the Control & Automation System
