March 2017 - Carlo Gavazzi is pleased to announce the new WM20 Three-Phase Power Analyzer, an exciting 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) 3-phase power analyzer which can be used for single, two and three phase systems. 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 a large, bright 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 new ‘rotating pages’ function automatically shows all measurements in a sequence without having to scroll manually through the keypad. The WM20 Power Analyzer can be used as a stand-alone meter or as a part of a complete VMUC-based energy management system. This analyzer can be used in a wide number of applications, ranging from building automation (for monitoring of the mains or sub-metering) to industrial automation (for monitoring variables and consumption of a single machine, or for the mains of an entire manufacturing facility). The features of the WM20 Power Analyzers include: Modular meter Class 0.5S (kWh) Accuracy ±0.2% RDG (current/voltage) Comprehensive 4 line LCD display Optical port for programming and data logging Optional digital output module Alarms can be linked to relay outputs Optional communication module Choice of protocols; Modbus (RS-485, TCP/IP), BACnet (RS-485, TCP/IP) and Profibus cULus listed and CE marked Free downloadable configuration software

Since CARLO GAVAZZI has so many types of energy meters, we’ve created a simplified one page flyer to select the most cost effective three phase meter (and possibly a web based solution) for mounting on a DIN Rail, or on the outside door of an electrical enclosure: WM20/EM24 Flyer

We have also created this handy flyer showing the difference between the WM20, WM30 and WM40 Series products: WM20/30/40 Comparison Flyer

The WM20 Power Analyzers are available from Carlo Gavazzi’s North American network of sales offices, distributors, and online at www.GavazziOnline.com.
