Servo Motor / VFD Combo Filter SF20032

OnFILTER' Servo Motor / VFD Filter SF20032

This filter qualifies for UL 508A panels by being certified to UL1283 and/or UL/IEC60939 Standards

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), SF20201 (20A), or DIN rail mounted SV20101 models.
