Description
Active power filter module is used in active power filter device, which is a kind of closed type indoor electrical equipment. This kind of filter device is widely applied to high and low voltage electrical appliance factory, switch factory, electric instrument and power transformer manufacturer and so on.
This type of APF module is designed based on years of application experience and customers comments, which can monitor load current in real-time and output the compensation current which is equal with harmonics with contrary phase to realize the function of eliminating harmonics and ensure the power system operating safely and effectively.
