2.5 3000A Power Module Description
The 3000A Power Module is supplied in the configurations shown in table 2.5. The
3000A Power Module has the following features:
• The 3000A Power Module uses twelve SCRs in the armature bridge to convert the
3-phase AC input to a DC output. The SCRs are built into a heatpipe assembly that
is cooled by the bridge fan.
• The 3000A Power Module is protected from incoming fault currents by a circuit
breaker or line fuses. The DC output is protected from fault currents by a DC
contactor. The components of the Power Module (the armature bridge, field bridge,
and control components) are protected by fuses, MOVs, snubbers, and/or chokes.
• The 3000A Power Module is constructed and housed in four bays. The first bay
contains the AC input and control hardware, the second bay contains the fuses, the
third bay contains the armature bridge hardware, and the fourth bay contains the
DC output hardware.
• The 3000A Power Module has a standard top-hat extension over the disconnect bay
for the AC input. The Power Module can also be built to allow an alternative input
entry, using an optional bottom-entry bay (on the left side of the disconnect bay).
Figures 2.9 and 2.10 show component locations and Power Module dimensions.
Please refer to these figures when installing or servicing the Power Module. Refer to
Appendix B for wiring diagrams of both the regenerative and non-regenerative
versions of the Power Module.
