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 High potential test voltage P -> E 4800VDC for 2 sec The FN 2211 / FN 2210 series are primarily designed P -> P 3600VDC for 2 sec for PV inverter applications between 250 and 2 300 A. Protection category IP00 However, they can potentially also be applied in other DC applications within published specifications, like Overload capability 4x rated current at switch on, max. 8 sec UPS, DC motor drives, energy/battery storage 1.5x rated current for 1 minute, once per hour systems, or DC charger installations.
