ACTIVE POWER FILTER(APF) 380V/690V-40%~+20% (THREE PHASE VOLTAGE)
Category: Power Quality
Active Power Filter is a new electric power harmonic management dedicated device, which adopts modern power electronics technology and the digital Signal processing technique in the Digital Signal Processor (DSP). This Filter can overcome the traditional Filter, like LC Filter etc. Shortcomings of harmonic suppression and reactive power compensation, achieve dynamic tracing compensation and fill the harmonic, reactive power. The main function is managing the current harmonic, Series active Filter is mainly managing the voltage harmonic.
Active Power Filter is widely applied for industry, commerce and organizations in power networks. Example, electric system, water treatment equipment, petrochemical enterprise, huge mall and office building, precision electronic enterprise, airport/port power supply system, medical institutions. According to different application object, active filter can ensure power supply reliability, reduce the interference and improve the product quality, increase equipment life, reduce equipment damage, and so on.
