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)
