Item Specification
AC-input type Autoranging input with power factor correction (PFC)
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.
AC-input voltage 100 to 240 VAC (±10% for full range)
AC-input current
• 12 A @ 100 VAC
• 6A @ 240VAC
AC-input frequency 50/60 Hz (nominal)
kVA rating 1188 kVA
