Buffalo Grove, IL – Carlo Gavazzi Inc has recently launched the EM21 Series. This very compact 3-phase energy meter is provided with an innovative detachable, connector-less and battery-less display, which allows the user to configure the instrument for panel mounting (72 x 72mm) or DIN-rail mounting, either as an energy meter or a transducer. Typically the transducer would only be DIN rail mounted, whereas the meter could be DIN rail mounted or panel mounted, therefore this is truly three energy devices in one housing.

This general purpose three phase energy meter is suitable for both active and reactive energy metering for cost allocation, but also for main electrical parameter measurement and retransmission (transducer function). Current measurements are carried out by means of external current transformers. Voltage measurements carried out either by means of direct connection (up to 400VLL) or by means of potential transformers. The EM21 Series is provided with a pulse output for active energy retransmission. As an option, a two-wire RS485 communication port is also available. The EM21 Series is compact and easy to install, thanks to its application-oriented programming procedure, downloadable setup software and the wrong phase-sequence warning. Some of the main technical features include:
