Voltage monitors (digital)
The Wagner digital voltage monitors provide continuous monitoring of the power and control signals used to operate any 1 or 3 phase load. Protected devices can include motors, pumps, fans, compressors and other devices.
The voltage monitors protect these devices by keeping a constant watch over the supplied voltage, and when the voltage goes outside of a voltage and tolerance that you select, the monitor opens its control relay.
