The Carlo Gavazzi WM40AV53H is a modular three-phase power analyser designed for accurate electrical measurement, energy monitoring and power analysis in industrial and commercial installations. As part of the Carlo Gavazzi WM40 series, it provides a flexible platform for monitoring electrical networks with optional communication and I/O modules for integration into energy management and automation systems.
This panel-mounted analyser is built for switchboards, control panels and electrical distribution systems where reliable measurement of voltage, current, power, energy and system performance is required. Its modular design allows the unit to be adapted to different site requirements using optional communication modules including Modbus, Ethernet, BACnet and Profibus options.
With voltage inputs covering 220–400 V L-N and 380–690 V L-L, plus 5 A current transformer input, the WM40AV53H is suitable for monitoring a wide range of three-phase electrical networks. Its 100–240 V AC/DC auxiliary supply makes it ideal for integration into modern control cabinets and building automation systems.
Power analysers such as the Carlo Gavazzi WM40AV53H help engineers, panel builders and facilities teams monitor electrical consumption, system loading and power conditions across three-phase networks. By measuring key electrical parameters, the analyser supports improved visibility of energy usage and helps identify load imbalance, inefficiency and abnormal operating conditions.
The WM40 series is designed around a modular architecture, allowing the base analyser to be expanded with communication and I/O modules to suit different project requirements. This makes the WM40AV53H a practical choice for industrial monitoring, building management systems, switchboard metering and energy efficiency projects.
