HLMU Series Information

  • Protects against phase loss & reversal; over, under & unbalanced voltages; & over & under frequency
  • Encapsulated circuitry
  • Isolated, 10A, DPDT output contacts
  • LED indicates relay status, faults, & time delays
  • Universal line voltage 200 to 480VAC in one unit
  • Compact design
  • Finger‑safe terminal blocks, up to 12 AWG
The HLMU Series is a universal voltage, encapsulated, 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 and loss; over, under and unbalanced voltages; 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 200ms when phase loss is detected. Adjustable time delays are included to prevent nuisance tripping and short cycling of sensitive equipment. The isolated, 10A, DPDT 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 setpoint and the acceptable frequency range are fixed. Both delta and wye systems can be monitored; no connection to neutral is required
