5. Power Supply
This document defines the requirements for a universal input switching power supply, which pro-
vides 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
