VLT Low Harmonic Drive

Danfoss Industries offers VLT Aqua Drive, VLT automation drive and VLT HVAC drive, available in low harmonic versions. Where the performance of other low harmonic technologies depends on the stability of the grid and load or affect the controlled motor, the new Danfoss VLT low harmonic drives continuously regulate the network and load conditions without affecting the connected motor. VLT low harmonic drives are motor friendly, with output impulse and shaft voltages compatible with motors conforming to IEC 60034-17/25 and NEMA-MG1-1998 Part 31.4.4.2), as per standard VLT drives. The VLT low harmonic drive has the same modular build-up as our standard high power drives. The VLT low harmonic drive meets the toughest harmonic recommendations and gives the user full readout of the unit performance towards the grid, including graphical overview of grid behaviour. The perfect solution for meeting the toughest harmonics recommendation/standards, generator-powered installations, installation with generator backup, soft power grids, installation of drives in grids with limited excess power capacity. Voltage range: 380-480 V AC, 50-60 Hz. Power range: 132-630 kW high overload/160-710 kW normal overload (matching drive frames D, E and F). Enclosure degree: IP 21/Nema 1, IP 54 hybrid.
