The Carlo Gavazzi WM20AV63H 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 networks while supporting expansion through optional plug-in modules.
This panel-mounted analyser is ideal for switchboards, control panels and energy management systems where dependable measurement and communication flexibility are required. The WM20AV63H 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 5 A current transformer inputs, the WM20AV63H is well suited to lower voltage measurement applications, generator systems, machinery panels and energy monitoring projects. Its 100–240 V AC/DC auxiliary power supply provides flexible installation options for industrial environments.
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 WM20AV63H is especially suitable for systems requiring a lower voltage measurement range combined with standard 5 A CT inputs. 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.
