The Danfoss VLT® Low Harmonic Drive is the first solution combining an active filter and a drive in one package.
The VLT® Low Harmonic Drive continuously regulates harmonic suppression according to the load and grid conditions without affecting the connected motor.
The total harmonic current distortion is reduced to less then 3% on grids with balanced mains, a minimum pre-distortion to less than 5% on grids with high harmonic distortion and 2% phase unbalance. The VLT® Low Harmonic Drive meets all present harmonic standards and recommendations.
