EMC - RFI

Onboard EMC Filter

An internal EMC filter is provided as standard with the Unidrive . It is adequate for most industrial applications. The filter conforms to EN61800-3 (second environment) when motor cable length does not exceed a certain length depending on the model.

 

External EMC Filters

EMC filters are used to minimize high frequency power supply line disturbances caused by PWM AC drives that may interfere
with proper operation of sensitive electronic equipment. These specific filters have been assessed for conformance with the
EMC directive by testing with the appropriate Control Techniques drives.

 

Mounting Style

  • Bookend: filter mounts next to the drive with the smallest dimension being the width of the filter
  • Footprint: filter mounts between the drive heatsink and the panel or enclosure
  • Block: filter mounts on the panel near the drive

Optional External EMC Filters
