Cisco C4KX-PWR-750AC-R Catalyst 4500-X 750W AC Front-to-Back Cooling Power Supply.

AC-input type

Autoranging input with power factor correction (PFC)

AC-input voltage

100 to 240 VAC (115/230 VAC nominal) single-phase

AC-input current

•11 A @ 100 VAC (max)
•6 A @ 200 VAC (max)

AC-input frequency

47 to 63 Hz (50/60 Hz nominal)

Branch circuit requirement

Each chassis power supply should have its own dedicated, fused-branch circuit:

•For North America—15 A
•For International—Circuits should be 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.

Power supply output capacity

750 W

Power supply output

•12 VDC @ 62 A
•3.3 VDC @ 3 A

Output holdup time

16 ms minimum (20 ms @ 60% load)

BTU (total output)

1122 BTU/hour (nominal)
1365 BTU/hour (max)
