Features and benefits

■

Compact general purpose

three-phase and neutral line EMC ﬁ lter

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.

Three-phase and neutral line filter for

general purpose four-wire filtering

Compact space-saving design

Choice of connection style

Low operating leakage current

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.
