Energy Meter, Compact 3-Phase, 120 to 230VAC Input Range, 18-260VAC Supply RS485
Three-phase energy meter with removable front LCD display unit. The same unit can be used either as a DIN-rail mounting or a panel mounting energy meter. This general purpose three phase energy meter is suitable for both active and reactive energy metering for cost allocation but also for main electrical parameter measurement and retransmission transducer function. Housing for DIN rail mounting with IP50 front protection degree. Current measurements carried out by means of external current transformers and voltage measurements carried out either by means of direct connection or by means of potential transformers. EM21-72D is provided, as standard, with a pulsating output for active energy retransmission. In addition a 2-wire RS-485 communication port is available as an option.
