Product description
EM3-DIN is a three-phase
energy meter for the measure
of active or reactive energy;
the 208V
L-L
, 220V
L-L
and
400V
L-L
meters are self-sup-
plied, while the 660V
L-L
meters
are provided with auxiliary
power supply. EM3-DIN is
provided with: 6+1DGT elec-
tromechanical indicator for
the indication of kWh or
kvarh; one green LED for the
indication of power ON; one
red LED blinking proportional-
ly to the consumed energy.

Only open collector outputs: the grounds of the outputs are separated, and therefore it’s possible to carry out, for the same module,
two different connections. The load resistance (Rc) must be designed so that the closed contact current is lower than 100mA; the
VDC voltage must be lower than or equal to 30V.
