2000 400A, 60Hz Ferroresonant Rectifier J85503C-3
2 - 12 Product Description
Issue 10 July 2000
Circuit
Modules
The rectifier's signal processing and control circuitry are located on
replaceable circuit modules or packs. Circuit modules are plug-in boards
that are ordered separately. (See Section 3 for ordering information.) All
modules are accessible by opening the rectifier door.
Figure 2-2 shows the location of the modules and other features of the
rectifier. Figures 6-2, 6-3, 7-1, and 5-6 show the CM1 through CM4
board layouts, respectively.
Table 2-A provides a description of each module.
CM1 (329A Fuse
Board)
The CM1 circuit module (329A Fuse Board) protects the control
circuits from faults in the rectifier power train. It contains alarm fuses,
bleeder resistors, access points for the plant shunt voltage, and an
isolated RFA transfer contact.
