FAFW series unitary active filter

These products allows to reinject a current corresponding to the total harmonic component (the first order). By this way, the network is traversed by a current equal to the single fundamental component.

Active filtering and power quality

The loads operated by electronic devices are increasingly adopted in more and more industrial and commercial applications such as: Variable Speed Drives, rectifiers, UPS systems, DC power supplies, welding machines, computers, TV, energy efficient lamps, photocopiers. These loads generate waveform distortions that become threats for network and components.

In particular voltage and current harmonics, where the latter is the most dangerous, generate a series of problems, like:

  • Heating cables
  • Undue tripping of circuit breakers
  • Blowing of fuses
  • Overloading of the capacitors and network resonance
  • Overload on the neutral cable
  • Premature aging transformers
  • Malfunction of electronic equipment

Features and benefits

FAFW is the new generation of active harmonic filters. It reliably mitigates harmonics and compensates voltage dips as well as reactive power. The FAFW analizes network disturbances and provides an opposing compensation current. In doing so, FAFW actively adapts to fluctuations and responds in less than half a millisecond. Its compact dimensions, simple installation, and digital intelligence allow for a quick and straight forward integration in the most diverse applications.

Reducing harmonics

These products allows to reinject a current corresponding to the total harmonic component (the first order). By this way, the network is traversed by a current equal to the single fundamental component.
