Schaffner, FN2200 400A 1200 V dc DC, Screw Mount EMI Filter, Tab, Single Phase

Schaffner FN 2200 series DC filters aid in the control of conducted emissions on the panel side of a PV inverter system, significantly reducing the potential for high-frequency interference panel radiation. The FN 2200 series filters also protect the solar panel from HF stray and leakage currents which can cause pre-mature aging in the PV modules. FN 2200 filters are primarily designed for PV inverters. However, they can potentially also be used in other DC applications within published specifications, such as UPS, DC motor drives or DC quick chargers.
