Modular power quality meter

The WM20 offers faster communications for building automation networks using Modbus, BACnet over RS 485 or TCP/IP and Profibus, as well as functions such as load monitoring measurement and comprehensive alarm management – all in a compact plug-and–play modular format that streamlines installation and simplifies inventory management. 

Made up of three components, the base unit provides a wide backlit LCD display and touch-panel to program auto-scroll of measurements display and configure parameter values and manages two virtual alarms and two accessory modules, one using digital outputs, the other for communication.  

The digital output module with static or relay outputs can be associated with alarms or transmit pulses proportional to energy consumption, while the communication module allows you to configure the analyser and transmit data using a different communications protocol.

Applications run from cost allocation and control, through complex cost and power analysis of both the conventional energy market and building and industrial automation.

As with other Carlo Gavazzi energy meters and analysers, the WM20 carries CE marking and UL certifications.
