3-phase + neutral line lters
FN 256
Compact general purpose
three-phase and neutral line EMC lter
Approvals
■
Three-phase and neutral line filter for
general purpose four-wire filtering
■
Compact space-saving design
■
Choice of connection style
■
Low operating leakage current
Typical applications
■
FN 256 filters are designed specifically for
applications involving asymmetric loads,
ranging from industrial controls to medical
electronics systems. These typically involve
insufficiently filtered converters and
switch-mode power supplies on different
phases, causing current imbalance and
significant interference problems.
■
Employing single-stage filter circuits for
each phase and the neutral line, FN 256 fil-
ters provide high attenuation of both sym-
metrical and asymmetrical interference.
■
Used as a mains input filter, FN 256 filters
also increase conducted immunity and
thus contribute to overall system reliability.
■
Choice of connection style as well as filter
ratings in line with common fuse values
support a fast and easy application-specific
filter selection and deployment.
■
A light weight aluminium housing with a
small footprint ensures that the filters can
be easily accommodated on control panels
and in tight power cabinets.
