The TB8100 PMU is made up of a number of individual boards and cards
which comprise two main modules, the AC module and the DC module.
The auxiliary power supply board is optional.
The PMU is available in three main hardware configurations:
AC PMU (AC input only)
DC PMU (DC input only)
AC and DC PMU (both the AC and DC modules are fitted to allow both
AC and DC inputs).
The table below provides an overview of the major mechanical differences
between these three configurations.
AC converter board is mounted
on special brackets which also
cover the holes normally covered
by the AC module heatsinks; only
the current sense and output filter
circuitry is placed on the board

Note
For the sake of simplicity and clarity, the instructions and illustra-
tions in this chapter refer to the AC and DC PMU. However, the
AC PMU and DC PMU can be disassembled and reassembled
using the same basic procedures and techniques.
