Carlo Gavazzi EM21-72D Panel or DIN Rail Meter with Pulse and Modbus output (AV53.X.0.S.X)

CT Ratio programmable up to 9999A

£90.00

£108.00 inc VAT

Overview

This meter has a removable screen, and so can be used as a 72 x 72mm panel meter or as a standard DIN rail. 

You can order this meter with RS485 Modbus communications and also with an MID approval (As seen in our commercial billing category)

This general purpose three phase energy meter is suitable for 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 400 V LL) or by means of potential transformers.

The EM21 Series is provided with a pulse output for active energy re-transmission. As an option, a two-wire RS-485 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
