Overview of Active Power Filter APF-1000

APF-1000 Active power filter has various compensation modes (harmonic, reactive power, three-phase unbalance and capacitor switching control), which can simultaneously make the said various compensation, and the proportion of compensation capacity by harmonic, reactive power, and three-phase unbalance can also be set, comprehensively solving the problem of power quality of the low-voltage distribution side;

Working mode Harmonic compensation, reactive power compensation, three-phase load unbalance compensation, and capacitor switching control.
Harmonic filtering The device can filter out 2nd to 50th order harmonics at the same time, and harmonics can be filtered out for specific times between 2nd to 50th order.
Current limit The compensating current is automatically limited within the rated current range.
Compensation effect Total harmonic current distortion rate (THDi) < 5%;
Reactive power factor > 0.99
Three-phase unbalance degree < 5%;
