The Carlo Gavazzi WM30AV43H is a smart 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 WM30 series, it provides advanced monitoring for electrical networks while supporting expansion through optional I/O and communication modules.
This panel-mounted analyser is suitable for switchboards, control panels and energy management systems where reliable measurement and flexible integration are required. The WM30AV43H supports optional communication modules including RS485 Modbus RTU, Ethernet Modbus TCP/IP, BACnet and Profibus, making it suitable for automation systems, building management networks and industrial monitoring platforms.
With voltage inputs of 220–400 V L-N and 380–690 V L-L, plus 1 A current transformer inputs, the WM30AV43H is ideal for three-phase distribution systems, machinery panels and energy monitoring projects. Its 100–240 V AC/DC auxiliary power supply provides flexible installation options for industrial and commercial environments.
Power analysers such as the Carlo Gavazzi WM30 are used to measure voltage, current, power, frequency, power factor and energy usage across electrical installations. This allows engineers, facilities teams and panel builders to monitor load behaviour, improve energy visibility and support preventative maintenance.
The WM30AV43H is especially suitable for systems requiring high voltage measurement, 1 A CT inputs and flexible communication options. Its modular architecture allows communication and I/O modules to be added as required, making it suitable for standalone monitoring as well as integration into wider automation and energy management systems.
