EM3-DIN is a three-phase energy meter for the measure of active or reactive energy. The 208VL-L, 220VL-L and 400VL-L meters are self-sup-plied, while the 660VL-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.
The EM3-DIN is a three‑phase energy meter designed for measuring active and reactive energy. It offers electromechanical 6+1 DGT display, LED indicators, and selectable energy display via dip‑switch. Optional output modules provide pulse or relay/open‑collector outputs for external interfacing.
The device can be powered from the mains (115 VAC or 230 VAC, 50‑60 Hz) or from a self‑powered configuration. It complies with EN 61036 (Class 2 active energy) and EN 61268 (Class 3 reactive energy) and meets IEC‑664 installation category III requirements. Mechanical dimensions are 162.5 × 90 × 63 mm and the housing is made of ABS/NORYL/PC with IP40/20 protection.
