Description
Autoranging input with power factor correction (PFC)
Note
Low-line (120 VAC nominal)—90 VAC (min) to 132 VAC (max)
•
• High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)
12 A @ 120 VAC
•
6 A @ 230 VAC
•
50/60 Hz (nominal)
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.
