3 Phase Voltage Monitor
WVM Series
Motor Protector
The WVM Series provides protection against premature equipment (motor) failure caused by voltage faults on the 3 Phase Line. The WVM’s microcontroller design provides reliable protection even if regenerated voltages are present. It combines dependable fault sensing with a 10 fault memory and a 6 LED status display. Part instrument, part control, the WVM protects your equipment when you’re not there and displays what happened when you return. The WVM is fully adjustable and includes time delays to prevent nuisance tripping and improve system operation. Time delays include a 0.25 to 30 s adjustable trip delay, an adjustable 0.25 to 64 m (in 3 ranges) restart delay, plus a unique 3 to 15 s true random start delay. The random start delay prevents voltage sags caused by simultaneous restarting of numerous motor loads after a power outage.

    • Phase Loss & Reversal
    • Over, Under & Unbalanced Voltages
    • Short Cycling

Universal 3 Phase Voltage Monitor
DLMU & DLMH Series (SPDT & N.O. or N.C.)
Motor Protector
The DLMU Series is a universal voltage, 3 Phase Voltage Monitor. It continuously measures the voltage of each of
the three phases with microcontroller accuracy and compares the value to preset trip points. It separately senses
Phase Reversal, Over, Under and Unbalanced voltages including Phase Loss and over or under frequency. Protection
is assured during periods of large average voltage fluctuations or when regenerated voltages are present. The unit
trips within 200 ms when phase loss is detected. Adjustable time delays are included to prevent nuisance tripping
and short cycling of sensitive equipment. The 10A isolated SPDT and 2A alarm output relay contacts trip when a
phase voltage exceeds the trip limits for the trip delay. Nominal line voltage, voltage unbalance, and time delays
are knob adjustable. The phase loss set point and the acceptable frequency range are fixed. Both Delta and Wye
systems can be monitored; no connection to neutral is required.
