      KY-50-APF
      Active Power Filter


      Products Features

      harmonic compensation

      It can filter 2~50 harmonics at the same time, or set the compensation times of harmonic current and the compensation rate of each harmonic selectively according to the need

       

      Reactive power compensation

      Capacitive sensibility (-1~1) infinite compensation, PF1.00 perfect reactive power compensation effect.

       

      Three phase unbalance compensation

      Three-phase active power unbalance compensation, three-phase reactive power unbalance compensation, phase separation compensation.

       

      Learning function

      The original intelligent Fourier algorithm can automatically learn the grid environment and system impedance, effectively avoid system shock, so that the system can achieve the most stable compensation state.

       

      Harmonic monitoring

      In the process of load change, if there is resonance, the equipment will automatically judge and exit the system, and alarm at the same time to avoid failure.

       

      Temperature monitoring

      Monitor the temperature of ABC three-phase heating device (IGBT and inductor) in real time, when the temperature is too high, it will issue an overtemperature alarm, and automatically shut down to stop compensation.
