The first solution to combine an active filter and a drive in one package
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.
The VLT® Low Harmonic Drive continuously regulates harmonic suppression according to the load and grid conditions without affecting the connected motor.Power Range 160-710 kW250-1000 HPVoltage range 380 – 480 VAC 50 – 60 Hz
The following options are available:
With VLT® Motion Control Tool MCT 31, you can determine whether harmonics will be an issue in your installation when drives are added.
MCT 31 estimates the benefits of adding various harmonic mitigation solutions from the Danfoss product portfolio and calculates system harmonic distortion. Furthermore the software provides quick indication of whether the installation complies with the most recognized harmonic norms and recommendations.
