Cisco CATALYST 6509E 9 SLOT 15U CHASSIS NO POWER SUPPLY NO FAN TRAY Specification Guide

 lists the specifications for the 2700 W AC-input and DC-input power supplies.

AC-input type

Autoranging input with power factor correction (PFC).

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)

Power supply output capacity

1350 W maximum (100–120 VAC)

2700 W maximum (200–240 VAC)

1350 W maximum (–48 to –60 VDC, with one DC 
input)

2700 W maximum (–48 to –60 VDC, with two DC 
inputs)

System power dissipation

3.4 KVA (high-line operation; AC-input)

3.5 KW (DC-input)

DC-input voltage

–48 VDC to –60 VDC continuous
