1.2 HARDWARE AND EQUIPMENT FEATURES
Figures 1-1, 1-2, and 1-3 illustrate the three typical hardware configurations of the
ADDvantage-32 PLUS Power Converters. Each hardware configuration contains a
microprocessor board, bridge interface board, and a power base. Hardware configuration
varies with the output rating of the ADDvantage-32 PLUS being used.
Figure 1-4 shows a typical Advanced Firing Module. The AFM hardware generally
includes the same items listed above except for the power base.
