The FN 3311/FN 3310 poduct series of standard EMC/
EMI filters are based on Schaffner’s many years of
expertise in filter design for all types of converter and
inverter applications. Installed between the PV
inverter and the power grid, the FN 3311/FN 3310 AC
filters are used to influence positively the conducted
emissions on the grid side to help to comply with the
required emission standards.
Performance indicators
Features and benefits
The FN 3311/FN 3310 series are the most compact
dedicated high current AC filters, not only suitable for
PV applications, but being an optimum fit with most
modern PV inverter topologies. In addition the filters
can be configured in a very flexible way to fulfil
custom specific application requirements. All FN
3311/FN 3310 come in unsymmetrical housings,
which help to prevent inverse installation and wrong
electrical connection. Along with solar panel-side
installed Schaffner DC EMC/EMI filters FN 2211/FN
2210, the AC filters FN 3311/FN 3310 are key to meet
the stringent international standards for electro-
magnetic compatibility and help to ensure a reliable
and fault-free operation of the entire PV system.

The FN 3311/FN 3310 series are primarily designed for
all kind of power line connected converter and
inverter applications between 250 and 2'300 A.
However, they are optimised for PV inverter and can
potentially also be applied for general purpose motor
drives applications.
