The WM30-96 Smart Modular Power Analyzer from Carlo Gavazzi 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 Smart Modular Power Analyzer from Carlo Gavazzi 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 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 used for pulse (proportional to the active or reactive energy) and/or alarm outputs. The WM30-96 offers four communication options: RS485, RS232, Ethernet and BACNet-IP; as well as relay, transistor and analog outputs. Some of key technical specifications include:
