PQMII-C | GE Fanuc | Power Quality Meter

Description

The PQMII-C is a high-precision, multi-functional power quality meter from the GE Fanuc PQMII series, designed for comprehensive monitoring and analysis of electrical grid performance. It tracks critical parameters including voltage, current, power, harmonics up to the 50th order, and transient events, enabling users to detect and resolve grid issues such as harmonic distortion, voltage fluctuations, and transient disturbances to enhance equipment reliability and stability. Key technical specifications include a measurement range of 0 to 600VAC for voltage and 0 to 20A AC for current, with a power factor range of 0.001 to 1.000 and an overall accuracy of ±0.2% of reading. It operates within a frequency range of 45Hz to 65Hz, and features a wide working temperature range of -20 degrees Celsius to +85 degrees Celsius. Equipped with 64 channels (32 analog inputs and 32 analog outputs), it offers flexible connectivity via RS-485 (Modbus compatible), Modbus DNP3.0, and Ethernet (Modbus TCP/IP compatible) interfaces. The unit has a large log memory capable of storing up to 1024 samples per cycle, and comes in a standard size of 225mm x 165mm x 85mm with a weight of approximately 2.5kg. Ideal for medium-voltage networks, transformers, capacitor banks, generators, and motors, it supports continuous three-phase network monitoring, programmable threshold alarms, and integration with PLC systems as a data concentrator.
