The VLT low-harmonic drives ensure high-quality sine waves from the power-supply grid by actively imposing currents, as needed.

The VLT low-harmonic drives ensure high-quality sine waves from the power-supply grid by actively imposing currents, as needed.
The drives come in 132 to 630-kW high overload, 160 to 710-kW normal overload, and voltage range of 380 to 480 Vac, 50 to 60 Hz. The units are suitable for generator-powered installations, or those with generator back-up power; soft power grids, and grids with limited excess power capacity.

The VLT drives produce no motor winding stress; no impact on bearing life; and provide users with full readout of unit performance towards the grid, including a graphical overview of grid behavior. The drives continuously regulate the network and load conditions without affecting the connected motor.
