The device is capable of sensing instantaneous electrical variables, harmonic distortion and energy generation or consumption. It can also be configured for single-, two- or three-phase systems.

Carlo Gavazzi’s WM20 Three-Phase Power Analyzer assists manufacturers who are looking to monitor and manage energy demands. It is available in four versions for managing up to 600 VAC power and is supplied with either a one- or five-amp current transformer input.

The analyzer features a comprehensive four-line liquid crystal display, optional communication modules and a choice of Modbus (RS-485, TCP/IP), BACnet (RS-485, TCP/IP) or Profibus communication protocols. An optical port for programming and data logging, digital output modules and alarms that can be linked to relay outputs are also available. The device is suitable for use as a stand-alone meter or as a system component of a complete VMUC-based energy management system.
