Allen-Bradley 1756-PA72 AC Power Supply 85-265VAC

Allen-Bradley 1756-PA72 ControlLogix AC Power Supply accepts 85–265 VAC input and provides a regulated 5 V DC output to the 1756 backplane, enabling reliable operation of ControlLogix chassis across a broad range of line voltages. This standard AC input supply is designed to mount to the left side of a typical 1756 chassis (examples include 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17) and powers the backplane and connected I/O modules. The PA72 delivers 5 V DC at up to 10 A, supporting typical ControlLogix configurations in industrial automation environments. As part of Rockwell Automation's PA family of power supplies, the PA72/C variants align with installation guidelines and chassis compatibility documented in Rockwell's product data and selection guides for ControlLogix systems. This power supply is commonly used to backpower 1756 chassis in machine control panels, OEM automation setups, and retrofit projects where a broad input voltage tolerance and compact footprint are priorities.
