2700 W Power Supply Specifications
Table A-11 lists the specifications for the 2700 W AC-input and DC-input power supplies.
Table A-13 2700 W Power Supply Specifications
Specification Description
AC-input type Autoranging input with power factor correction (PFC).
Note Power factor correction is a standard feature on
all Catalyst 6500 series AC-input power
supplies. PFC reduces the reactive component
in the source AC current allowing higher power
factors (typically 99 percent or better) and
lower harmonic current components.
AC-input voltage 100 to 120 VAC, 200 to 240 VAC (±10% for full range)
AC-input current 16 A maximum at 200 VAC at 2700 W output
16 A maximum at 100 VAC at 1350 W output
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)
