Apr. 18, 2017 - Carlo Gavazzi has introduced the WM20 three-phase power analyzer, describing it as a new product range targeted to assist manufacturers and end-users 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, says the company, adding that it is capable of measuring most relevant 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 by one of the available 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 through the keypad. The WM20 can be used as a standalone meter or as a part of a complete VMUC-based energy management system. According to the company, the unit can be used for various industrial automation applications, including monitoring variables and consumption of a single machine or for the mains of an entire manufacturing facility.
