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 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 meas-
urement and retransmission
(transducer function). Possibility to display also exported
active energy (e.g. in case of
regenerated energy in lifts or
similar applications) harmonic distortion information are
available for the voltages and
the currents, up to the 15th
harmonic. An hourcounter
meter is available to link the
energy consumption to the

relevant working hours and
an hourcounter to link the
exported energy to production hours. Housing for DINrail mounting with IP40 (front)
protection degree. Current
measurements carried out
by means of external current
transformers transformers,
5A or 333mV (CTV series), or
ROG4K, Rogowski coil solution without external integra-
tor. Voltage measurements
carried out either by means
of direct connection or by
means of potential transformers. EM210 is provided,
as standard, with a pulsating output for active energy
retransmission. In addition a
2-wire RS485 communication port is available as an
option.
