SYSTEM DESCRIPTION

Power Supply Module The Power Supply Module is a single self contained assembly mounted on the rear panel. This module provides:

￿Unregulated +5, +9, ± 18, and ± 27 Vdc supply voltages to the other assemblies of the 372XXB.

￿Dedicated AC line connection for the Internal VGA Monitor.

￿Thermal and over-current shutdown protection circuitry

￿Sensing and input power regulation for operation with

85 – 264 VAC, 48 – 63 Hz, universal AC line input power.

￿Internal fan cooling (for power supply module)

￿Supply voltages distribution

Table 7-1 identifies all 372XXB DC power supply voltages and lists their usage by the various PCB assemblies. Unless otherwise indi- cated, supply voltages are regulated on the assembly using them. The analog and digital power supply grounds are isolated.

NOTE

All power supply voltages listed in Table 7-1 can be ac- cessed via the A/D bus for measurement by the the A/D converter circuitry (e.g., DVM) located on the A5 A/D PCB assembly.
