The Carlo Gavazzi WM40AV63L is a modular three-phase power analyser designed for accurate electrical measurement, energy monitoring and power quality analysis in industrial and commercial installations. As part of the Carlo Gavazzi WM40 series, it provides a scalable solution for monitoring electrical systems while supporting optional communication and I/O modules for seamless integration into automation and energy management platforms.
Designed for installation in electrical switchboards and control panels, the WM40AV63L measures voltage, current, active and reactive power, energy consumption, frequency, power factor and harmonic distortion. Its modular architecture allows the analyser to be expanded with communication interfaces and accessory modules to suit a wide variety of industrial monitoring applications.
Supporting 57.7–133 V L-N and 100–230 V L-L electrical systems with 5 (6) A current transformer inputs, the WM40AV63L is powered from a 24–48 V AC/DC auxiliary supply. It is ideal for industrial machinery, energy management systems, commercial buildings and electrical distribution panels requiring dependable energy measurement and system diagnostics.
The Carlo Gavazzi WM40AV63L continuously measures essential electrical parameters, enabling engineers and maintenance teams to monitor energy consumption, detect abnormal operating conditions and optimise system performance. Advanced measurement capabilities help improve energy efficiency while supporting preventative maintenance programmes.
The WM40 platform is fully modular, allowing communication, digital I/O and analogue expansion modules to be added as system requirements evolve. This flexibility makes the analyser suitable for new installations as well as retrofit energy management projects.
