-VLT® Low Harmonic Drive — the first solution to combine 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.
Power Range
160-710 kW
250-1000 HP
Voltage range
380 – 480 VAC 50 – 60 Hz
Unique features such as sleep mode and back channel cooling offers unmatched energy efficiency for Low Harmonic Drives
The VLT® Low harmonic drive requires the same set-up and installation as a standard VLT® drive and out of the box it ensures optimum harmonic performance
The VLT® Low harmonic drive has the same modular build-up as our standard high power drives and shares similar features: Built-in RFI filters, coated PCB and user-friendly programming
