PWR-C45-2800ACV/2  Specification

AC-input type

Autoranging input with power factor corrector

AC-input voltage

200 to 240 VAC (±10% for full range)

AC-input current

16 A maximum at 200 VAC

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:

For North America—15 A or 20 A

For International—Circuits sized to local and national codes

All Catalyst 4500 E-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.
