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
.
