The PLMU Series Family

The PLMU Series continuously measures the voltage of each of the three phases to provide protection for 3-phase motors and sensitive loads. Its microcontroller senses under and overvoltage, voltage unbalance, phase loss, and phase reversal. Protection is provided even when regenerated voltages are present. Universal voltage operation and standard base connection allows the PLMU to replace hundreds of competitive part numbers.

Operation
Upon application of power, a 0.6s random start delay begins and the PLMU measures the voltage levels and line frequency and selects the voltage range. The output relay is energized and the LED glows green when all voltages are acceptable and the phase sequence is correct. LED flashes green during trip delay, glows red when output de-energizes. Undervoltage, overvoltage, and voltage unbalance must be sensed for continuous trip delay before the relay de-energizes. Re-energization is automatic upon fault correction. The output relay will not energize if a fault condition is sensed as 3-phase input voltage is applied. The LED alternately flashes red/green when phase reversal is sensed. Line voltage is selected with the knob, setting the over and under voltage trip points. Voltage range is automatically selected by the microcontroller.

Features:

  • Protects against phase & reversal; & over, under & unbalanced voltages
  • Octal plug-in
  • Isolated, 10A, SPDT output contacts
  • Operates from 200 to 480VAC
  • LED indicator glows green when voltages are acceptable, red for faults
  • Indicates reverse-phase wiring
  • Simple 3-wire connection for delta or wye systems
  • ASME A17.1 Rule 210.6
  • NEMA MG1 14:30, 14:35
  • IEEE C62.41-1991 Level B
