PERATION
The AC power supply module is capable of operating in either standalone or in
groupings of parallel, and multi-phase output configurations. This allows
extending the power, voltage, and current ratings while minimizing the number of
unique modules comprising a system. When configured in groups, the modules
are programmed and controlled as single, virtual channels. All configuration
setup within the modules for implementing groups is performed automatically.
However, the output power and remote sense leads must be appropriately
hardwired before issuing the grouping commands.

TANDALONE
O
PERATION
Modules operated in standalone mode function as independent AC power
supplies. The outputs are isolated from adjacent modules, and either output
terminal may be grounded, or left floating with respect to the chassis ground.
The Mainframe backplane control and data communications interface is also
isolated; therefore, there are no restrictions as to the physical location of a
module within the Mainframe when it is operated in standalone mode.

ARALLEL
O
PERATION
Operation of modules in a parallel group requires routing of analog control
signals through the backplane between the modules, as well as the digital
control/communications, to implement a master/slave control interface. The
routing of signals in this interface requires that parallel modules must be
located in a contiguous physical group; no intervening modules (which are not
part of the parallel group) are allowed to be located within the parallel group.
Empty slots can separate individual modules of the group, and the group can
be extended between two Mainframes. The outputs of the modules must be
hardwired externally, while all internal control signal connections are configured
automatically when the parallel group is set up through software. The remote
sense leads are connected to all the modules of the group. The parallel group
is programmed as a “virtual” module, equivalent to a single module with the
combined current rating of the parallel group of modules. Modules must be set
to the same output range when paralleled.

PERATION
Modules could be operated in a multi-phase group regardless of their location
in the ReFlex Power™ system. The multi-phase group does utilize the analog
control signals of the back plane, as well as the digital control/communications,
to implement a master/slave control interface. The outputs and remote sense of
the modules must be hardwired externally, while all internal control signal
connections are configured automatically when the multi-phase group is set up
