The WM20 is a modular class 0.5S (kWh) power analyser able to measure all the main electrical variables, including the harmonic distortion of currents and voltages. The variables can be controlled with 2 virtual alarms, optionally linked to digital outputs.

All the information gathered is available on a large, clear LCD display and can be transmitted by one of the available protocols, including Modbus, BACnet and Profibus.

This analyser can be used in a wide number of applications, from Building automation (monitoring of mains or of each single floor/department/office distribution panel) to Industrial Automation (monitoring variables and consumption of single machines).
