Why Choose the Carlo Gavazzi WM20AV43H Power Analyser?
The Carlo Gavazzi WM20AV43H is a smart modular three-phase power analyser designed for accurate energy measurement, electrical monitoring and power analysis in industrial and commercial installations. As part of the Carlo Gavazzi WM20 series, it provides flexible monitoring for single-phase, two-phase and three-phase electrical networks.
This modular analyser is designed for panel-mounted applications where reliable measurement and future expansion are required. The WM20AV43H supports optional I/O and communication modules, allowing the analyser to be adapted for remote monitoring, alarm signalling, pulse outputs and integration with automation or building management systems.
With voltage inputs of 220–400 V L-N and 380–690 V L-L, plus 1 A current transformer inputs, the WM20AV43H is suitable for higher voltage three-phase installations, switchboards, machinery panels and energy management systems. Its 100–240 V AC/DC auxiliary power supply provides flexible power connection options for industrial environments.
