A Simple, Compact and Easy to Install 3-Phase Energy Meter: IT is The New EM21-72D by Carlo Gavazzi

 

An innovative device, that can be used for both BMS and cost allocation applications


Carlo Gavazzi Automation, the international electronics Group with activities in the design, manufacturing and marketing of electronic equipment, launches EM21-72D : this three-phase energy meter is provided by a detachable display, that allows configuring the instrument for panel (only 72x72mm) or DIN-rail mounting, either as an energy meter or a transducer. EM21-72D is compact and easy to install, thanks to its application-oriented programming procedure and the wrong phase-sequence warning.

“We are proud to say Carlo Gavazzi is providing the first energy meter based on a detachable, connector-less and battery-less display:thanks to this innovative solution EM21-72D will confirm our Group in its leading position as provider of cutting edge products.

EM21-72D is the ideal product to be sold through all sales channels and we believe it will become the best-seller energy meter, notices Fabio D’Incà - International Product Manager.

EM21-72D, developed by the Belluno (Italy)Controls team, offers three and selectable set of variables to be displayed. Moreover, all the electrical parameters of the installation can be immediately available, via the RS485 port,either to the BMS (Building Management System)or to the standard acquisition-monitoring system.
