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
• Low-line (120 VAC nominal)—85 VAC (min) to
132 VAC (max)
• High-line (230 VAC nominal)—170 VAC (min) to
264 VAC (max)
AC-input current
• 16 A @ 120 VAC
• 8 A @ 230 VAC
kVA rating 1.625 kVA
Branch circuit requirement (AC-input) Each chassis power supply should have its own
dedicated, fused-branch circuit:
• For North America—15 A or 20 A
• For International—Circuits sized to local and
national codes
• All Catalyst 6500 series AC-input power supplies
require single-phase source AC.
• 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.
