The FC filters provide filtering for frequency inverters and
variable speed motor drives. Designed for very noisy
applications, they attenuate conducted interference at low
and high frequency ranges and protect programmable
logic controllers from RF noise on the AC power line. These
filters perform best when installed on the line side of the
motor drive. The FC filters better prevent noise from
returning to the line, enabling equipment to meet strict
European regulations on RFI.
Suited for field wiring applications, these filters are ideal for
EMC troubleshooting and field refurbishing. The FC filters
feature side flanges for easy mounting and DIN type
terminals which eliminate live metal parts, allowing safer
and easier connection. The filters could also be sold as an
accessory to motor drives marketed into Europe.
