950 W AC-Input and DC-Input Power Supplies Appendix A Power Supply Specifications Table A-3 950 W AC-Input and DC-Input Power Supplies Specifications (continued) Item Branch circuit requirement (AC-input) Power supply output capacity DC-input voltage DC-input current Power supply output (AC supply) Power supply output (DC supply) Output holdup time Heat Dissipation Specification Each chassis power supply should have its own dedicated, fused-branch circuit: • For North America-15 A • For International-Circuits sized to local and national codes • All Catalyst 6500 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. - 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. 950 W maximum (100-240 VAC) -48 VDC to -60 VDC continuous • 38 A @ -48 VDC • 30 A @ -60 VDC • 15 A @ +1.5 V • 2.5 A @ +3.3 V • 19.15 A @ +50 V • 15 A @ +1.5 V • 2.5 A @ +3.3 V • 19.15 A @ +50 V • 20 ms minimum (AC-input power supply) • 4 ms (DC-input power supply) • 4441 BTU/hour (approx.) AC-input power supply • 4632 BTU/hour (approx.) DC-input power supply Catalyst 6500 Series Switches Installation Guide A-6 OL-5781-04
