Important note
FN 5030 are additional common-mode modules. They can NOT work alone! FN 5030 have to be operated downstream of a regular (symmetrical) sine wave output filter. Possible combinations are FN 5020/FN 5030 for motor frequencies up to 600Hz, or FN 5010/FN 5030 for max. 70Hz.
For additional information please consult the Schaffner application note „Sinus Plus − New Output Filter Concept for Power Drive Systems“.

General purpose four-pole (1500r/min) AC induction motor rated 480V/50Hz.
Exact value highly depends upon the motor cable type and length, switching frequency, motor frequency and further stray parameters within the system. Please contact your local Schaffner partner
