The Carlo Gavazzi WM30AV43L is a smart modular three-phase power analyser designed for precise electrical measurement, energy monitoring and power quality analysis in industrial and commercial installations. As part of the advanced Carlo Gavazzi WM30 series, it provides comprehensive monitoring of electrical systems while offering exceptional flexibility through optional communication and I/O expansion modules.
Designed for modern switchboards and control panels, the WM30AV43L supports a wide variety of single-phase, two-phase and three-phase electrical networks. Its modular architecture allows the analyser to be expanded with optional communication protocols including Modbus RTU, Modbus TCP/IP, BACnet and Profibus, making it suitable for integration into industrial automation and building management systems.
With voltage inputs from 220–400 V L-N and 380–690 V L-L, together with 1 A current transformer inputs, the WM30AV43L is ideal for industrial distribution systems, machinery, commercial buildings and energy management applications. The unit operates from a 24–48 V AC/DC auxiliary power supply and features a backlit LCD display with an optical programming port for simple configuration.
The Carlo Gavazzi WM30 series enables accurate monitoring of electrical parameters including voltage, current, power, frequency, harmonics and energy consumption. This allows engineers to optimise system performance, reduce operating costs and improve preventative maintenance strategies across industrial and commercial installations.
Thanks to its modular design, the WM30AV43L can be customised with communication and I/O modules as application requirements evolve, making it an ideal long-term solution for energy management, automation and power quality monitoring.
