      PQM-T20-C-A

      Spare Part Number

      PNMultin

      Product Information:

      The PQM-T20-C-A is a GE Fanuc PQM II series Power Quality Meter, designed for monitoring and analyzing electrical power systems in industrial, commercial, and utility applications. It provides real-time measurement of electrical parameters to evaluate power quality and help identify issues in electrical distribution systems.


      This device measures a wide range of electrical values, including voltage, current, frequency, active power, reactive power, apparent power, power factor, and energy consumption. It also performs power quality analysis such as total harmonic distortion (THD), voltage sags, swells, and transient event detection, making it suitable for applications that require accurate and continuous power monitoring.


      In terms of communication and integration, the PQM-T20-C-A supports RS-232 and RS-485 serial interfaces, typically using Modbus protocol to connect with SCADA systems, PLCs, or energy management systems (EMS). It also includes configurable relay outputs and analog I/O options for alarms, control functions, and remote monitoring. This model is now a legacy/discontinued product, mainly used for maintenance and replacement in existing installations.
