Active Power Filter(APF) Cabinet

Product Features:

Improve three phase imbalance Improve power factor Harmonic filter efficiency up to 97.5% Up to 8 modules in parallel operation max Compensate harmonic filter order: 2 to 50 Automatic current limitation with no overload Easy to choose the model, only need to measure harmonic filter current Response time <10ms Regular input voltage: 380V±20% Special input voltage such as 480V, 690V and etc can be customized OEM orders, distributors and agents are welcome.


APF Working Principle:

FSNOAH series active power filters are parallel harmonic compensation device. It monitors the load current in real time with an external current transformer, the internal DSP calculates the harmonic content of the load current and sends the control signal to the inverter. The control inverter generates a harmonic current injected into the grid, which is equal to the harmonic current of the load and opposite direction, and realizes the active filtering function.
