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.
– For high-line operation, the power supply
operates with the hot conductor wired to a
source AC phase and the neutral conductor
wired either to ground or to another source AC
phase as long as the net input voltage is in the
range of 170 to 264 VAC.
– 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)
Power supply output capacity
• 1300 W maximum (100–120 VAC)
• 2500 W maximum (200–240 VAC)
• 2500 W maximum (–48 to –60 VDC)
System power dissipation 3520 W (total input power) or 3.6 KVA (high-line
operation)
DC-input voltage –48 VDC to –60 VDC continuous
DC-input current
• 80 A @ –40.5 VDC
• 70 A @ –48 VDC
• 55 A @ –60 VDC
