Product Description

Three-phase energy meter

with removable front LCD

display unit. The same unit

can be used either as a

DIN-rail mounting or a pan-

el mounting energy meter.

This general purpose three-

phase energy meter is suit-

able for both active and

reactive

for cost allocation but also

for main electrical parame-

ter

retransmission (transducer

function). Housing for DIN-

rail

carried out either by means

of direct connection or by

means of potential trans-

formers. EM21-72D is pro-

vided, as standard, with a

pulsating output for active

energy retransmission. In

addition a 2-wire RS485

communication

available as an option.
