Carlo Gavazzi three-phase power analyzer

March 1, 2017
This analyzer can be used in a number of applications, ranging from building automation for monitoring of the mains or sub-metering to industrial automation.

The WM20 three-phase power analyzer is meant to assist in monitoring and managing escalating energy costs. The WM20 is a modular class 0.5S (kWh) three-phase power analyzer which can be used for single, two and three phase systems. It is capable of measuring most instantaneous electrical variables, harmonic distortion and energy generation or consumption.

Four versions are available to manage up to 600 VAC systems with a choice of either a one or five amp current transformer input. All information gathered is available on an LCD display and can be transmitted via numerous communication protocols, including Modbus (RS-485, TCP/IP), BACnet, (RS-485, TCP/IP) and Profibus. The  rotating pages function automatically shows all measurements in a sequence without having to scroll manually. The WM20 can be used as a stand-alone meter or as part of the complete VMUC-based energy management system.
