LC SINE WAVE FILTERS

SMISEN Make Sinus Filters are best-in-class


filter delivering unequaled performance in
cleaning the PWM waveforms generated by
Variable Frequency Drives (VFDs).

They eliminates high frequency content and


voltage peaks, thereby reducing motor heating
to give you extended motor life – and less
downtime.

Our Sinus Filters also offers incredible reliability


and durability.
