Appendix A Power Supply Specifications 1400 W AC-Input Power Supply 1400 W Power Supply Specifications Table A-9 lists the specifications for the 1400 W AC-input power supply. Table A-9 1400 W Power Supply Specifications Specification AC-input type AC-input voltage AC-input current kVA rating Branch circuit requirement (AC-input) AC-input frequency Power supply output capacity Power supply output Description Autoranging input. Power Factor Correction (PFC) included. Note 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. 100 to 240 VAC (±10% for full range) • 16 A @ 100 VAC • 8 A @ 240 VAC 1.75 kVA 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. 50/60 Hz (nominal) (±3 Hz for full range) 1400 W • 15 A @ +1.5 V • 2.5 A @ +3.3 V • 27.4 A @ +50 V OL-5781-04 Catalyst 6500 Series Switches Installation Guide A-19
