Voltage Monitoring Relays - Preset
Voltage monitoring relays will trip switching operations whenever specified voltage levels are exceeded or not reached respectively. The time lag will mask out short-term deviations. Monitoring and control of complex processes will be facilitated through logical operation of the input signals with times and/or other digital signals. For example, they can be designed as a battery watchdog to cut out loads voltage-dependent to save the battery or facilitate motor starting.
