Servo Motor / VFD Combo Filter SF20032

OnFILTER' Servo Motor / VFD Filter SF20032

This patented model of servo motor/VFD EMI filter uniquely combines both motor and AC filtering in one small enclosure providing complete EMI filtering for a servo motor or VFD.   If you want only motor filter please consider SF20031 (3A), SF20101 (10A), or SF20201 (20A) models.
