AC/DC Shunt

Voltage Sensing Relay

The supply voltage must be provided to the LVM continuously. While the LVM will pick-up and drop-out based on the voltage set point, the voltage sensing inputs will accept up to 600 volts without damage. With no voltage on the voltage sensing input, the internal relay is energized, transferring the output contacts. When the sensed voltage exceeds the set point, the output relay will de-energize. With no supply voltage the output relay is de-energized. Hysteresis and a time delay prevent rapid cycling of the output relay.
