Operation
Parallel operation is used to obtain a higher current through a single output using two
or more supplies. Set all of the outputs to the same voltage before connecting the
positive (+) output terminals and negative (-) output terminals in parallel. See
Figure 3.23
. The total current available is the sum of the maximum currents of each
supply.
Notes:
1. Set the OVP trip level to the same point for all of the paralleled supplies.
2. When operating multiple supplies in parallel, the operating mode of each supply
will depend on the load current being drawn. For example, with two 60V-50A
output power supplies operating in parallel with a 75A load, one supply will
operate in constant current mode supplying 50A and the other supply will
operate in voltage mode supplying the remaining 25A.
