The Carlo Gavazzi WM40AV63H is a modular three-phase power analyser designed for precise energy monitoring, electrical measurement 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, SCADA and building automation systems.
This panel-mounted analyser is built for electrical distribution panels, switchboards and control cabinets where reliable measurement of voltage, current, power, energy and system performance is required. Its modular construction enables expansion with optional communication modules such as Modbus, Ethernet, BACnet and Profibus, allowing it to be adapted to a wide range of monitoring applications.
With voltage inputs covering 57.7–133 V L-N and 100–230 V L-L, plus 5 A current transformer input, the WM40AV63H is suitable for low-voltage three-phase monitoring applications using CT-based measurement. Its 100–240 V AC/DC auxiliary supply makes it a practical choice for modern control panel and automation installations.
Power analysers such as the Carlo Gavazzi WM40AV63H help engineers, panel builders and facilities teams monitor electrical consumption, system loading and power conditions across low-voltage electrical 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 WM40AV63H a practical choice for industrial monitoring, building management systems, switchboard metering and energy efficiency projects.
