PWR-C45-1400AC Specification

AC-input type

Autoranging input with power factor corrector

Note Power factor correction is a standard feature on all Catalyst 4500 E-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

16 A @ 120 VAC

7 A @ 240 VAC

AC-input frequency

50/60 Hz (nominal) (±3 Hz 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.

Not supported

LEDs and Meanings

INPUT OK

Green—Source AC voltage is OK. (Input voltage is 85 VAC or greater.)

Off—Source AC voltage falls below 70 VAC, is not present, or the power supply is turned off.

FAN OK

Green—Power supply fan is operating properly.

Off—Power supply fan failure is detected.

OUTPUT FAIL

Red—Problem with one or more of the DC-output voltages of the power supply is detected.

Off—DC-output voltage with acceptable margins.

Note For proper operation of the OUTPUT FAIL LED, systems with single power supplies must be configured with a minimum of one fan tray assembly and one supervisor engine. Systems with dual power supplies must have a minimum configuration of one fan tray assembly, one supervisor engine, and one additional module. Failure to meet these minimum configuration requirements can cause a false power supply output fail signal.
