VLT Sine-wave Filter MCC 101 output filters are differential-mode low-pass filters that suppress the switching frequency component from the drive and smooth out the phase-to-phase output voltage of the drive to become sinusoidal. This reduces the motor insulation stress and bearing currents.
By supplying the motor with a sinusoidal voltage waveform, the switching acoustic noise from the motor is also eliminated.
Parallel filter installation is possible for applications in the high power range
Eliminates over-voltages and voltage spikes caused by cable reflections
Reduces electromagnetic interference by eliminating pulse reflection caused by current ringing in the motor cable. This allows the use of unshielded motor cables in some applications
