Why Choose the Carlo Gavazzi WM20AV73L Power Analyser?
The Carlo Gavazzi WM20AV73L 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 while supporting expansion through optional plug-in modules.
This panel-mounted analyser is ideal for switchboards, control panels and energy management systems where reliable measurement and communication flexibility are required. The WM20AV73L supports optional I/O and communication modules, allowing it to be configured for remote monitoring, alarm signalling, pulse outputs and integration with automation or building management systems.
With voltage inputs of 55.7–133 V L-N and 100–230 V L-L, plus 1 A current transformer inputs, the WM20AV73L is well suited to lower voltage measurement applications, generator systems, machinery panels and energy monitoring projects. Its 24–48 V AC/DC auxiliary power supply makes it suitable for installations using low-voltage control supplies.

Modular Energy Monitoring for Lower Voltage Systems
Power analysers such as the Carlo Gavazzi WM20 are used to measure voltage, current, power, frequency, power factor and energy usage across electrical installations. This enables engineers, facilities teams and panel builders to monitor load behaviour, improve energy visibility and support preventative maintenance.
The WM20AV73L is especially suitable for systems requiring a lower voltage measurement range combined with 1 A CT inputs and a low-voltage auxiliary supply. Its modular architecture allows communication and output modules to be added as required, making it suitable for standalone monitoring as well as integration into wider automation and energy management systems.
Typical Applications
- Industrial electrical panels and switchboards.
- Energy management and monitoring systems.
- Generator and lower voltage electrical monitoring.
- Machinery and production line power analysis.
- Power distribution and load monitoring.
- Automation systems requiring expandable communication options.
