1000 W Power Supply Specifications
Table A-7 lists the specifications for the 1000 W AC-input power supply.
Table A-7 1000 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
• 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
• 12 A @ 120 VAC
• 6 A @ 230 VAC
AC-input frequency 50/60 Hz (nominal)
Branch circuit requirement 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.
