VLT® Low Harmonic Drive
Danfoss Drives launches the first mass produced VLT® Low Harmonic Drive.
The 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 other VLT® drives, the Low Harmonic Drive is built on a highly modular technology platform basic the elements that proved their functionality, quality and overall reliability in other parts of the broad VLT® drives program.
