Specification Description
AC-input type Autoranging input with power factor correction (PFC)
Power factor correction (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 5 A
AC-input frequency 50/60 Hz (nominal) (±3% for full range)
