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.

Branch circuit requirement (AC-input)
Each chassis power supply should have its own
dedicated, fused-branch circuit:

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
