Product Description
Product Description
Product name: Wall mounted reactive power compensation module ahf automatic harmonic filter
Active power filter is a new type of electronic device for dynamic filtering of harmonic wave and reactive power compensation. It 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.
