Modular Active Power Filter is a power filter device that can monitor load current and fliter harmonics in real-time to maintain a clean line current. it montors 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 PF and compensate reactive power.


  • Eliminate 2nd to 50th harmonics (Selectable)
  • Steplessly compensate both inductive & capacitive reative power
  • Imbalance correction
  • Fast, can track dynamic reactive power (<0.1ms)
  • Actual output capacity is the same as reated capacity
