            Mains Chokes

            General                                                                                                                   Mains choke 3L

            In special cases, if mains voltage is more than 3% asymmetrical, then the AKD-48A must be used with a mains choke.        A number of drives can be connected to the same mains choke; the rated current of the mains choke must be greater than or at
                                                                                                                                      least equal to the total current of the connected drives.
            Purpose of mains choke:                                                                                                                                                                                                                SER
              •  Prevents impermissible loading of semiconductors in the event of rapid current rise during commutation.                                                                                                                           V
              •  Prevents voltage dips in the mains voltage caused by commutation.                                                                                                                                                                 O
              •  Reduces current ripple in the DC link, thereby increasing the service life of the DC link capacitors.                                                                                                                             DRIVE A
