Product Description
How to orderEM21 72R VV5 3 X O X X
Three-phase energy meter with removable front LCD display unit. The same unit canbeusedeitherasa 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 energy metering for cost allocation but also for main electrical parame- ter measurement and retransmission (transducer function). Housing for DIN- rail mountingwithIP50
(front) protection degree. Current measurements car- ried out by means of exter- nal miniature split-core cur- rent sensors (included) and voltage measurements car- ried out either by means of direct connection or by means of potential trans- formers. EM21-72R is pro- vided,as standard,witha pulsating outputfor active energy retransmission. In addition a 2-wire RS485 communication port is available as an option.
