Voltage monitoring modules monitor 1- and 3-phase systems up to450 V AC/DC.
Relay contacts are available on the output side for direct under-voltage or over-voltage monitoring. By monitoring the voltage you can continually control individual devices or sub-systems. Any discrepancies or voltage interruptions in the supply circuits can be evaluated as an operational malfunction. Targeted steps to rectify the problem can then be initiated.
