Three-phase energy meter with removable LCD display unit.
The same device can be used as a DIN-rail or panel-mounted energy meter.
The main features of this three-phase energy meter are the measurement of active and reactive energy at cost
monitoring and measurement and transmission of the most common electrical quantities (transmitter function).
Enclosure class DIN rail installation IP50 (from the front)
External, small-sized, openable current transformers are used for current measurement, and for voltage measurements
either direct connection or voltage transformers are used. The EM21-72R meter has a standard pulse output, energy
to the transfer of consumption. In addition, the meter can be optionally equipped with a 2-wire RS485 serial port.
