Features and benefits
Typical applications
FN 2200 range of standard EMC/EMI filters
FN 2200 are the most compact dedicated DC
FN 2200 are primarily designed for PV invert-
ers. However, they can potentially also be
used in other DC applications within pub-
lished specifications, like UPS, DC motor
drives, or DC quick chargers.
is based on Schaffner’s years of experience in filters for PV inverters in the industry and
custom filter design for the global photovoltaic therefore support the integration in the ever
(PV) inverter industry. Installed between the
PV inverter and the solar panel, FN 2200 DC
filters help to control conducted emissions
shrinking frame sizes of today’s power elec-
tronics. All FN 2200 come in unsymmetrical
housings, which help to prevent inverse
on the panel side of the system and therefore installation and wrong electrical connection.
significantly reduce the potential for high-
frequency (HF) interference radiation off
the panel. The filter also protects the solar
panel from HF stray and leakage currents
which can cause pre-mature aging in the PV
modules.
Along with grid-side installed Schaffner AC
EMC/EMI filters, FN 2200 are key to meet
the stringent international standards for
electromagnetic compatibility (EMC) like EN
61000-6-3 and -6-4 and help to ensure a reli-
able and fault-free operation of the entire PV
system.
FN 2200 are designed for very low power
loss, to support overall PV system efficiency.
