Schaffner AC EMC/EMI filter FN 3xxx3.
- Installed between the PV inverter and the solar panel, the FN 2211 HV and FN 2210 HV 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 (HF) interference radiation of the panel.
- The filter also helps to prevent premature panel aging because of HF stray and leakage currents.
The FN 2211 HV/FN 2210 HV series are primarily designed for PV inverter applications between 250
and 2'300 A. However, they can potentially also be applied in other DC applications within published
specifications, like UPS, DC motor drives, energy/ battery storage systems, or DC charger installations.
