The VLT Low Harmonic Drive is a complete VLT frequency drive built on the power and control platform of the new generation VLT drives. The difference is that the VLT Low Harmonic Drive eliminates the harmonic disturbances on the supply grid by actively imposing currents into the grid so that the high quality sine wave of the grid current is restored.

Like the other VLT frequency drives, the VLT Low Harmonic Drive has a modular build-up and a  high energy efficiency, back-channel cooling and user-friendly operation.

The VLT AQUA Drive, VLT HVAC Drive and VLT AutomationDrive are available in this new low harmonic version.
