FN3310 / FN3311 Series EMC/EMI Filters

Schaffner’s many years of expertise in filter design for all types of converter and inverter applications are the basis for the FN3310 / FN3311 series of standard EMC/EMI filters. When installed between the PV inverter and the power grid, the AC filters are used to positively influence the conducted emissions on the grid side to help to comply with the required emission standards.

The FN3310 / FN3311 series are the most compact dedicated high-current AC filters, not only suitable for PV applications, but an optimum fit with most modern PV inverter topologies. In addition, the filters can be configured in a very flexible way to fulfill specific custom application requirements. All FN3310 / FN3311 come in asymmetrical housings, which help to prevent inverse installation and wrong electrical connection. Along with solar panel side installed Schaffner DC EMC/EMI filters FN2210 / FN2211, the AC filters FN3310 / FN3311 are key for meeting the stringent international standards for electromagnetic compatibility and help to ensure a reliable and fault-free operation of the entire PV system.

These filters are primarily designed for all kinds of power-line-connected converters and inverter applications between 250 A and 2300 A. However, they are optimized for PV inverters and can potentially also be applied for general-purpose motor drive applications.
