Features and benefits
Typical applications
■ General purpose 4-wire filtering
■ High power office equipment
■ Power supplies
■ UPS
■ Medical applications
■ Electrical cabinets
■ Control panels
■ 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 dif-
ferent 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 lightweight aluminium housing with a
small footprint ensures that the filters can
be easily accommodated on control panels
and in tight power cabinets.
