Allen Bradley 20-750-APS Auxiliary Power Supply

The AB 20-750-APS is a dedicated 24V auxiliary power supply module designed for use with PowerFlex 750-Series drives, including PowerFlex 753 and PowerFlex 755. This compact unit delivers 24V DC to support internal drive control circuits or maintain control power during main power loss.

The 20-750-APS mounts directly to the drive, offering plug-and-play installation with no separate wiring required. It ensures critical control functions, such as communication and diagnostics, remain active during downtime, startup, or transition to safe-state operation. Ideal for applications requiring safe motor control continuity and controller responsiveness in automation systems.
