DC interface chokes


Interface chokes (transition coils) ED2I (300Hz) are usually applied in multiphase systems to couple parallel operating rectifiers.
The following table lists only the sample parameters of some manufactured chokes. After the previous agreement there is a possibility to design chokes with parameters other than those given in the table.
