Allen-Bradley PowerFlex 4 AC Drives (22A)

This collection is for PowerFlex 4 drives with 22A catalog numbers. PowerFlex 40 drives use 22B: the similar names and numbering make the distinction worth checking before ordering.

Use the full 22A number to identify the supply and output configuration, then retain the original drive settings for installation. Rockwell's PowerFlex 4 and 40 technical data documents the two families. For 25B drives, browse PowerFlex 525.
