ONFIGURATION

The series output configuration could be combined with the parallel
configuration to produce a composite series/parallel configuration. Only
modules of the same model could be interconnected in series/parallel. The
restrictions listed in the sections on the series and parallel configurations
must be followed: the parallel modules must be physically contiguous, while
the series grouping is not location dependent. The outputs must be hardwired
as parallel groups connected in series. The remote sense leads are
connected only to the paralleling-master modules; ensure that single point
connections are maintained for the series connected sense leads. Figure
6-22
shows the series/parallel connection of six units with remote sensing.

The series/paralleled modules are programmed as a single, virtual channel
with a current rating equal to the sum of the number of modules connected in
parallel, and a voltage rating equal to the sum of the number of modules
connected in series. The master and slave supplies of a parallel group will
share the output current equally, while the series connected parallel groups of
modules will equally share the output voltage. Fault shutdown is coordinated
across all modules: a fault within any module of the group will result in
shutdown of all modules.

AUTION

To prevent damage to a supply, do not exceed the float voltage
specification limit for either of the output terminals to chassis.
