5. Power Supply

This document defines the requirements for a universal input switching power supply, which provides 750 watts DC with power factor corrected AC input and with current and remote sense reg- ulation. The power supply is used with its DC outputs paralleled with other identical supplies to form a redundant power system with system operating replacement capability (hot-swap). All power supply connectors, including AC and DC connectors, accommodate “blind mating.” The supply has four externally enabled outputs, one +5 V standby output at 1.0 A, and one +15 Vdc standby output at 200 mA. Both +5 Vdc and +15 Vdc standby outputs are present whenever AC power is applied. The four externally enabled outputs have the following ratings:

+3.3 Vdc at 36 A

+5 Vdc at 36 A

+12 Vdc at 36 A with 42 A peak

-12 Vdc at 1 A
