6.4.1
Amplifier Module (A4)
The amplifier module board is located perpendicular to the base heat sink of each power module.
This board contains the switching control logic and power devices of the power module.
6.4.2
Snubber Board (A5)
The snubber board is a small board located below the input electrolytic caps on the power board.
The snubber board connects directly to the power diodes which mount on an isolated mounting
plate between the transformer and the output inductor.
6.4.3
Output Filer Board (A6)
The output filter board is located in the back of each power module, directly above the output
electrolytic caps. One of the three power modules has an output filter board with external sense
connector. (5005-700-1) This module is always on the far right of the chassis. The other two
power modules (if present) have an output filter board without sense connections. (5005-700-2).
