Servo Motor / VFD Filter DIN Rail SV20101


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

"We tested the servo filter on another system, this time with Kollmorgen motors. We saw another significant reduction in noise on our signal"  (P.M.,U.K.)

Servo / VFD EMI filters help to substantially reduce EMI in the equipment and to protect motor's bearing from EDM-caused fluting.  These patented filters are complete multiple-mode filters, providing comprehensive noise reduction, not just reactors.

DIN rail mount SV20101 is most suited for motors consuming up to 10A.  Our chassis-mounted servo/VFD filters offer up to 20A version.   If you are looking to include an AC input filter for the drive, please see our chassis-mounted combo model which combines in one small package both motor and AC filters.

All specifications are subject to change without notice

If you are not sure which specific model would work with your drive/motor, send us a legible photo of drive and/or motor label and if you know, the specific models
