Parallel units“ (-1BD0 bzw. -0BD0)for connecting in parallel have the same technical data as the corresponding "basic units"(-1BA0 bzw. -0BA0). Please note the unit correspondence and notes of Section 3.7 (of the operating instructions for air-cooled rectifier units or rectifier/regenerating units)!

The permissible output current in parallel mode is reduced (due to current division between the power sections) by 10 % as compared to the sum of the rated currents of the separate power sections.

1) For units from product status A2 and onwards (labelling on the unit at the coolant connection).
