Connecting Supplies in Parallel
In most cases, units can be connected in straight parallel mode as shown in Figure 4-6 without any master/slave distinction,
and without any wiring to the analog connectors. This is possible because of the relatively high output impedance of each
unit. All units that are connected in straight parallel mode must be programmed with identical I-V curves or table data.
Remote sensing may be employed on all units if desired, but in many cases will have only a minimal effect on performance
due to the high output impedance of each unit.
If, for some reason, it is required that the output currents of all paralleled units be accurately matched, then you must use
auto-parallel connections as described in the following paragraphs.
