Specification & Technical Parameters

Electrical Characters

1.Measurement

3-phase voltage, 8 loops of 3 phase load current in one circuit, active power, active energy, frequency, power factor.

Auxiliary power supply:self-powered;

Consumption:≤5W;

Start-up current:0.004Ib,.When the current is 0.0004Ib and power factor is 1.0, the meter can start-up and be continuous recording.

Shunt running:With anti-shunt running logic circuits. When 115% voltage and no current, the meter output should not be more than one pulse.
