Three-phase energy meter with removable front LCD display unit.Thesameunitcanbe used either as a DIN-rail mounting or a panel mounting energy meter. This general pur- pose three-phase energy meter
is suitable for bothactive and reactive energymetering for cost allocation but also for main electrical parameter mea- surement and retransmission (transducer function). Housing for DIN-rail mounting with IP50
(front)protectiondegree. Cur- rent measurements carried out by means of external current transformers and voltage mea- surements carried out either by means of directconnectionor bymeansofpotentialtrans-
formers. EM21-72D is provid- ed, as standard, with a pulsat- ing output for active energy retransmission. In addition a 2- wireRS485communication port is available as an option.
