Parallel units (-1AD0) of size K for connecting in parallel have the same technical data as the corresponding
"basic units" (-1AA0). Please note the unit correspondence and notes of Section 3.7!
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.
