„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).

2)If the cooling circuits of the two converters are connected in parallel.

3)A rectifier/regenerating unit consists of two converters in separate housings.
