Why Choose the Carlo Gavazzi WM20AV43L Power Analyser?
The Carlo Gavazzi WM20AV43L 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 WM20 series, it provides flexible monitoring for single-phase, two-phase and three-phase electrical systems.
This modular analyser is designed for panel-mounted applications where reliable measurement and expansion flexibility are required. The WM20AV43L supports optional I/O and communication modules, allowing the unit to be adapted for alarm outputs, pulse signalling, remote monitoring and integration with building management or automation systems.
With voltage inputs of 220–400 V L-N and 380–690 V L-L, plus 1 A current transformer inputs, the WM20AV43L is suitable for low-voltage three-phase distribution panels, machinery systems and energy management applications. Its 24–48 V AC/DC auxiliary power supply makes it ideal for installations using low-voltage control supplies.
