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 electromechanical indicator for
the indication of kWh or
kvarh; one green LED for the
indication of power ON; one
red LED blinking proportionally to the consumed energy
.
