IEC inlet filters
FN 329
Performance IEC inlet filter
Approvalsn Rated currents up to 6A
n Integrated earth line choke
n Optional medical versions (B type)
Typical applications
The FN 321 IEC inlet filter combines an
IEC inlet and mains filter with excellent filter
attenuation in a small form factor. The FN 329
performance power entry module offers
additional EMI suppression for the earth line.
Choosing the FN 329 compact power entry
module brings you the rapid availability of a
standard filter associated with the necessary
safety acceptances. Standard IEC connector
filters are a practical solution helping you to
pass EMI system approval in a short time. A
wide selection on current ratings, output
connections and low leakage versions for
medical applications helping you to select the
desired solution for your application.
