Parallel Mode
If it is necessary to increase the total current, the power supply outputs must be wired
in parallel. The maximum total current is the sum of the individual currents of all sour-
ces connected in parallel. The output voltages for the individual outputs should be set
to the same voltage value as precisely as possible. For slight voltage differences, it is
common in this operating mode to first charge a voltage output up to the current limit;
the other voltage output provides the remaining current. See
For power supplies that are connected in parallel, it is possible that compensating cur-
rents flow within the power supplies. The use of power supplies by other manufactur-
ers, which are potentially not overload proof, can cause destruction of these units as
currents may be distributed unevenly.
