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

Wiring diagrams (optional module)

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.
