VLT® Advanced Active Filter AAF 006

  • The flexible filter for central/decentral harmonic mitigation

    The VLT® Advanced Active Filter AAF 006 improves system efficiency and increases grid robustness to avoid downtime. It can compensate for individual drives or it can be installed as a compact standalone solution at a point of common coupling to compensate for several loads simultaneously.

    The active filter ensures optimal harmonic suppression independent of the number of loads and their individual load profile. In addition, it corrects the power factor and balances the phase load to provide optimal energy utilization.
