Active Power Filter features simultaneously filter out 2 to 50 times harmonics, or select 2 to 50 times to compensate for any frequency harmonic response time of less than 300μs use 3DSP + CPLD digital control and international brands high speed IGBT, closed loop control, precise application of the four-phase line harmonic filter technology that eliminates neutral current automatically eliminate resonance and impedance from power system harmonic impedance change impacts have compensation; while compensating harmonics and reactive power; while compensating harmonics, no power and load three-phase current unbalance three modes of electronic overload protection with a machine inverter control fast FPGA, power digital signal processing functions modular design, easy to expand multi-parallel centralized monitoring remote network monitoring maintenance convenient, in line with the requirements of working environment, non-mechanical failures maintenance harmonic governance role independent control of active power filters in parallel parallel connection, not because of mechanical failure caused power grid power outage. YW-APF multiple parallel active power filter harmonic control system case, if one out of operation due to malfunction, the remaining machines still work to achieve filtering. Independent control of three-phase current independent control of each phase current harmonic control, single-phase injection current, regardless of system phase current imbalance affect the neutral filtering capacity of triple-phase lines. IP protection rating IP protection and lightning protection class IP20; lightning protection capability 20kA.
