3.4.2 Parallel
Parallel connection only allows thr connection of two or more power supplies of the same model to
obtain a higher current rating (maximum 24A for this power supply).
Figure 6 shows the parallel connection of two 3303D power supplies. One unit is set at 30V/3A and
the other at 20V/2.5A. Figure 7 shows the parallel connection voltage/current output versus load
changes.
