DATASHEET DC Filters FN 2211 and FN 2210
Compact high current DC EMC/EMI filter
Reduces conducted emissions towards the solar Approvals
panel
Reduces the probability of EMI radiation off the
solar panel
Helps to prevent premature panel aging
Helps to meet international EMC regulations
Most compact standard solution in the industry
FN 2210 without Cy capacitors to ground
The FN 2211 / FN 2210 series are the most compact
dedicated high current DC filters for PV inverters in
the industry and therefore are an optimum fit with
most modern PV inverter generation. In addition the
filters can be configured in a very flexible way to fulfil
customized application requirements.
All FN 2211 / FN 2210 come in unsymmetrical
housings, which help to prevent inverse installation
and wrong electrical connection. Along with grid-side
installed Schaffner AC EMC/EMI filters FN 2211 / FN
2210, the DC filters FN 2211 / FN 2210 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.
Features and benefits
Installed between the PV inverter and the solar panel,
the FN 2211 and FN 2210 DC filters are used to
influence positively the conducted emissions on the
panel side of the system. Therefore the DC filters
significantly reduce the potential for highfrequency
Technical specifications (HF) interference radiation of the panel. The filter also
helps to prevent premature panel aging because of
HF stray and leakage currents.
Maximum continuous operating voltage 1000 VDC
Operating frequency DC
Typical applications
Rated currents 250 to 2300 A @50C

Important note: depending on the grounding scheme of the solar power system, including the solar panel and the grid side transformer, the appropriate DC- and AC
EMC/EMI filter version need to be selected. For support, please contact your local Schaffner sales office or partner.
