The Carlo Gavazzi WM40AV73L is a modular three-phase power analyser designed for accurate energy monitoring, electrical measurement and power quality analysis in industrial and commercial installations. As part of the Carlo Gavazzi WM40 series, it offers a scalable solution for monitoring electrical systems with optional communication and I/O modules for seamless integration into automation, SCADA and energy management platforms.
Designed for installation in electrical switchboards and control panels, the WM40AV73L continuously measures voltage, current, active and reactive power, energy consumption, frequency, power factor and harmonic distortion. Its modular architecture enables the addition of communication interfaces and expansion modules, allowing the analyser to be tailored to a wide range of industrial monitoring applications.
Supporting 57.7–133 V L-N and 100–230 V L-L electrical systems with 1 (2) A current transformer inputs, the WM40AV73L is powered from a 24–48 V AC/DC auxiliary supply. It is ideally suited to industrial machinery, commercial buildings and electrical distribution panels where dependable energy monitoring and electrical diagnostics are essential.
The Carlo Gavazzi WM40AV73L continuously measures essential electrical parameters, enabling engineers and maintenance teams to monitor energy consumption, identify abnormal operating conditions and improve system efficiency. Advanced measurement capabilities support preventative maintenance while helping optimise electrical performance across industrial and commercial installations.
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 equally suitable for new installations and retrofit energy management projects.
