3-phase electricity consumption meter with SO

3-phase electricity consumption meter with SO

The LE-03d is a static (electronic) calibrated three-phase AC electricity meter in a direct circuit.

Operation
Under the influence of flowing current and applied voltage in each phase, a special electronic system generates pulses proportional to the amount of electricity consumed in this phase. Power consumption in the phase is indicated by the flashing of the corresponding LED (A, B, C). The sum of pulses from three phases signalled by LED flashing (800 pulses/kWh) is converted into energy consumed in the entire three-phase system and its value is indicated by a segment LCD display. The digit after the decimal point indicates the decimal parts (0.1 kWh = 100 Wh).

Note!
The meter has an S0+ – S0- pulse output. This allows the connection of another device reading pulses (S0) generated by the meter. For the correct operation of the meter, it is not necessary to connect an additional device.

The meter has the possibility to seal the input and output terminal covers to prevent bypassing the meter.
