General Electric PQMII Firmware: 73D224C4.000 Power Quality Meter

The General Electric Multilin PQMII is a three-phase power quality meter built for continuous monitoring of commercial, industrial, and utility power systems. It meters current, voltage, real and reactive power, energy use, power factor, and frequency, and runs harmonic analysis through the 63rd order with THD and TIF readings. Recording tools are built in: a voltage disturbance recorder that captures up to 500 sag and swell events, a 150-event recorder, and a 98,000-event data logger. Four assignable output relays and four switch inputs handle alarming, demand-based load shedding, and capacitor power factor correction control.

This listing is for one PQMII loaded with firmware 73D224C4.000, as identified in the listing title. The meter is operated from its keypad and illuminated 40-character display, and it connects over a front RS232 port and two rear RS485 ports with Modbus RTU and DNP 3.0 support, so it drops into existing SCADA and plant-monitoring networks.
