C6800-XL-3KW-AC= - Cisco Catalyst 6800 Switch Power Supply

AC-input type

Autoranging input with power factor correction.

AC-input voltage

Low-line (120 VAC nominal)—90 VAC (min) to 132 VAC (max)

High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)

AC-input current

16 A @ 240 VAC (3000 W output)

16 A @ 120 VAC (1300 W output)

AC-input frequency

50/60 Hz (nominal) (±3% for full range)

Branch circuit requirement

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

North America—20 A.

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.

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.
