Active Power Filter - Apf

Delta's Active Power Filter - APF2000 is a power filter device that can monitor load current and filter harmonics in real-time to maintain a clean line current. It monitors the load current in real-time using a current transformer and injects the exact opposite phase to the network of components that are to be filtered. It can also provide leading and lagging reactive current in real-time to improve the power factor and compensate reactive power.
