The FN 3311 HV/FN 3310 HV 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 3311HV and FN
3310HV AC filters are used to influence positively the
conducted emissions on the grid side to help to
comply with the required emission standards.
Features and benefits
The FN 3311 HV/FN 3310 HV 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 HV/FN 3310 HV come in unsymmetrical
housings, which help to prevent inverse installation
and wrong electrical connection. The AC filters FN
3311 HV/FN 3310 HV are key to meet the stringent
international standards for electromagnetic
compatibility and help to ensure a reliable and fault-
free operation of the entire PV system.

Typical applications
The FN 3311 HV/FN 3310 HV 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.
