Appendix A Power Supply Specifications
2500 W AC-Input and DC-Input Power Supplies
Branch circuit requirement (AC-input) Each chassis power supply should have its own
dedicated, fused-branch circuit:
• For North America—20 A
• For International—Circuits sized to local and
national codes
• All AC power supply inputs are fully isolated.
–
Source AC can be out of phase between
multiple power supplies in the same chassis,
which means that PS1 can be operating from
phase A and PS2 can be operating from
phase B.
–
Source AC can be out of phase between AC
inputs on power supplies that are equipped
with multiple AC inputs, which means that
power cord 1 can be plugged into phase A and
power cord 2 can be plugged into phase B.
AC-input frequency 50/60 Hz (nominal) (±3% for full range)
