Conducted EMI/RFI is a common reason equipment fails EMC certification. Understand common-/differential-mode noise and how DLC filters attenuate it to keep your drive within emission limits.
Match the DLC filter's WF model to your drive's input current (A) and output power (kW): single-phase S series 10–35 A, three-phase T series 6–990 A, three-phase + neutral TN series 6–170 A.
