Nancal Electric NC AH Series
Active Power Filter
NC AH Series Active Power Filter (APF) is a new type of power electronics with dynamic harmonic elimination (varying amplitudes and frequencies) and reactive power compensation (leading and lagging).
Applicable in various applications where the load varies.
  • low harmonic vfd
    Eliminate Harmonic

  • high power factor vfd
