              1. 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.
