The Kollmorgen Mains EMI Filters are line-side EMC filter units designed for installation between the AC supply and compatible servo drives to reduce conducted electrical disturbances on the mains and improve immunity to supply-borne interference.
Their construction combines chokes, resistors, and interference-suppression capacitors, with elements that address both common-mode and differential-mode noise. Within Kollmorgen drive systems, these filters are used where external mains filtering is required for EMC compliance, especially on drive variants that do not include an internal mains filter. The product family includes single-phase and three-phase versions in multiple current ratings for different supply voltages and cabinet power levels. These filters are intended for fixed industrial installations where correct grounding, cable routing, and filter sizing are necessary to maintain EMC performance and safe operation.
