VLT® Sine-wave Filters smooth the output voltage of a VLT® drive and reduce motor insulation stress and bearing currents as well as noise development in the motor.
For critical motors Use the filter especially for AC drive operation of older motors, low permitted voltages in terminal boxes or without phase insulation.
Long motor cables
Enable use of motor cables with a length of 500 m and more, using a sine-wave filter.
