Schaffner's new RV series of common mode chokes for electric vehicle (EV) charging stations offers designers a wide choice of power levels. This facilitates compliance with EMC standards early in the design process.
By offering a broad range and performance choices, the RV choke helps designers to minimize costs by being able to select a choke that tackles any electrical disturbances and noise and reduces them to the required compliance levels. The four performance choices in horizontal orientation are standard, standard plus (with increased height), small, and small with increased height. In vertical orientation they are standard, standard thin (with reduced core height), small and small thin (with reduced core height).
Compliance for UL Certification
Rated currents for the new choke are 16 A to 50 A per phase at 60 °C – delivering a significant amount of power – while rated common mode inductance levels range from 0.1 mH to 7.2 mH. In terms of certification, the RV series complies with UL/IEC 60938-1/-2 and UL 1446 E332676.
