Danfoss Drives – LHD (Low Harmonic Drive)

Vector CAG - Danfoss Drives Logo

The VLT® LHD 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.
