July 2020 – EMI-RFI Filters for VFDs and servo drives by GD Rectifiers

Published on: 16/07/2020

Discover our helpful selection guide on how to source the best EMI-RFI filters for your next project 


Enerdoor EMI-RFI Filters by GD Rectifiers


We’ve partnered with Enerdoor on providing a guide to selecting an EMI-RFI filter in conjunction with single or multiple variable frequency drives (VFDs) and servo drives.

Following the VFD and servo-drive specifications is not always sufficient to guarantee a system complies with the CE Certification and IEC Standards because components and systems as a whole have to adhere to less stringent Standards. Often enough, if a system is not meeting the correct Standard, installing an Enerdoor EMI-RFI filter will not only solve this issue, it will also exceed expectations.


Enerdoor’s EMI-RFI filters for VFDs and servo drives offer:

1)   On-site real time solutions

2)   Both in lab on-site testing is available

3)   Protects the entire machine instead of only the drive

4)   Low leakage current to avoid GFI interruption

5)   Fixed cost per project – with no extra charges

6)   Guaranteed solution


Enerdoor has been manufacturing EMI-RFI filters since 1992.  Their unique combination of being an EMI-RFI filter manufacturer and decades of experience with Enerdoor EMC mobile laboratories has allowed the manufacturer to comprise a list of filters compatible with the major variable frequency drive and servo drive manufacturers of the world.
