Product Name: SFR-APF Active Power Filter

Active power filter(APF for short) is a new type of electronic device for dynamic filtering of harmonic wave and reactive power compensation. 

APF can conduct real-time filtering and compensation to harmonic wave (both size and frequency are changed) and dynamic reactive power; and is used to overcome disadvantages of traditional harmonic suppression and reactive compensation methods of traditional filters, thus realizing systematic harmonic filtering function and reactive power compensation function. 

In addition, it is widely applied into power; metallurgy petroleum, port, chemical and industrial and mining enterprises.
