DC Power Filters to Control EMI-RFI Issues
DC-EMC filters are used to suppress unwanted electrical noise generated by electronic devices that operate on direct current (DC) power, helping ensure that these devices comply with EMI emission standards, do not interfere with other nearby electronic devices and ensure reliable operation. DC filters are specifically designed for DC power applications such as EV charging, DC grids, energy storage and PV installations.
As data transmission speeds increase and EMI-RFI issues multiply, TE has developed products to better solve the newer challenges communications companies encounter. Whether it's meeting FCC and international EMC standards on EMI-RFI emissions or developing a newly designed piece of equipment from being disturbed by EMI-RFI in the environment, a power line filter will help your equipment with compliance.

TE Schaffner’s FN2220, FN2230 and FN2240 DC Power Filters
The Global Automobile industry is currently going through a transition, introducing new Electric vehicles (EV) models every day. Today, EVs provide long-distance travel with infrequent stops at charging stations. For longer journeys, fast-charging stations reduce EV charging times to travel stop times that are convenient for users. Electromagnetic compliance (EMC) is vital at EV charging stations, for the EV, nearby wireless devices and for the power grid network. EMI filters prevent high-frequency noise generated by the rectification and power control processes during charging that might otherwise interfere with the vehicle or the power grid network. The TE Schaffner’s FN2220, FN2230 and FN2240 series enables EMC compliance and is vital for safe power in high voltage and high current fast chargers.
Electric vehicles use fast charging stations where high DC voltage and current are available to charge their batteries in a short time. The high voltage and current raise electrical safety and EMC compliance risks for the user, the EV and the power grid. The filters are designed to IEC 61851-23, intended to clean the power used to charge EVs at fast charging stations. Engineers around the globe are facing these and additional EMC standards. The performance, the resistance to ground, as well as the form factor, are adaptable, and make it easier for designers of charging stations to address EMI challenges.
