It is used for monitoring of voltage, power failure, sequence and asymmetry of phases in a 3-phase voltage system
Wide range of the monitored voltage with automatic selection of a lower/higher range
It measures actual voltage effective value - TRUE RMS
Fixed overvoltage level (Umax), adjustable undervoltage level (Umin)
Adjustable time delay (t2) for elimination of short-time voltage peaks
Adjustable time delay (t1) after switching on or with a return from the faulty state
Adjustable asymmetry level with optional switching off
Reset of the error in the memory using a pushbutton on the panel or external opening contact
