Smart Power Quality and Utility Analyzer


Carlo Gavazzi Inc. is proud to present its newest addition to their extensive Energy Management product lineup, the WM30-96, Smart Modular Power Analyzer. This innovative, three-phase power analyzer offers an upgraded LCD display, capable of showing four electrical variables, an energy counter and a power demand indicator at the same time.

     The WM30-96 is particularly recommended for utility metering, for both imported and exported energy, and  provides accurate electrical parameter measurements with 0.2% accuracy (current/voltage) and basic power quality analysis, up to the 32nd harmonic. Additionally, the analyzer can be provided with digital outputs that can be utilized for pulse (proportional to the active or reactive energy) and/or alarm outputs. The WM30-96 offers 4 communication options: RS485, RS232, Ethernet and BACNet-IP; as well as relay, transistor and analog outputs. Some of key technical specifications include:
•    Modular meter: main module plus up to three optional expansion modules
