Product description

EM3-DIN is a three-phaseenergy meter for the measureof active or reactive energy;the 208VL-L,220VL-Land400VL-Lmeters are self-sup-plied, while the 660VL-Lmetersare provided with auxiliary

power supply. EM3-DIN isprovided with: 6+1DGT elec-tromechanical indicator forthe indication of kWh orkvarh; one green LED for theindication of power ON; onered LED blinking proportional-ly to the consumed energy.System

Wiring diagrams (optional module)

Open collector output Fig. 1

Relay + open collecttor output Fig. 2

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; theVDC voltage must be lower than or equal to 30V.
