Carlo Gavazzi EM21 Series are general purpose three phase energy meters, suitable for both active and reactive energy metering for cost allocation, as well as for main electrical parameter measurement and retransmission. These meters are CE approved and also meet approval of Class B according to EN50470-3 (class 1 of EN62053-21) and Class 2 according to EN62053-23.

EM21 series meters are compact and extremely simple to install, due to their application-oriented programming procedure, downloadable setup software and  wrong phase-sequence warning. Meters benefit from a flexible installation, featuring a multi-use housing, for both DIN-rail and panel mounting applications.

Technical features include a high accuracy reading of ±0.5% and a robust IP50 protection rated housing. The innovative design contains a detachable LCD unit which displays a full set of instrumentation values (Voltage, Current etc).

As standard these meters are provided with a pulse output for active energy transmission and optionally, a two-wire RS485 communication port is also available. For more information on the EM21 energy meter, contact Bell Flow Systems on 0800 027 7786 or sales@bellflowsystems.co.uk.
