4.7.2 Configuring Multiple Supplies for Parallel 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 4-23. The total current
available is the sum of the maximum currents of each supply.
Note: When operating multiple supplies in parallel, the operating mode of each supply will
depend on the load current being drawn. For example, with two DCS 60-50E 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.
CAUTION!
To prevent internal damage to the supplies, ensure that the Over Voltage
Protection (OVP) trip level of all supplies is set to maximum.
CAUTION!
Remote sensing must not be used during parallel operation.
