Why Choose the Carlo Gavazzi WM20AV53L Power Analyser?
The Carlo Gavazzi WM20AV53L 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 of single-phase, two-phase and three-phase networks while supporting future expansion through optional plug-in modules.
This panel-mounted analyser is ideal for electrical switchboards, control panels and energy management systems where reliable measurement and modular communication options are required. The WM20AV53L 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 220–400 V L-N and 380–690 V L-L, plus 5 A current transformer inputs, the WM20AV53L is suitable for low-voltage three-phase distribution systems, machinery panels and commercial energy monitoring applications. Its 24–48 V AC/DC auxiliary power supply makes it well suited to installations using low-voltage control supplies.

Modular Energy Monitoring for Low-Voltage Electrical 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 WM20AV53L is especially suitable for switchboards and control panels where a low-voltage auxiliary supply is preferred. 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.
- Commercial building electrical monitoring.
- Machinery and production line power analysis.
- Power distribution and load monitoring.
- Automation systems requiring low-voltage auxiliary supply options.
