The Allen-Bradley 1746-P2 SLC 500 rack-mount power supply accepts 120/240 VAC input (47–63 Hz) and delivers a regulated 18–30 V DC output to the 1746 backplane, powering the SLC 500 rack without a separate DC supply. This compact unit fits in a standard 1746 rack and measures about 5.5 x 2.9 x 5.7 inches, with an operating temperature range of 0–60 C. Backplane current requirements are 5 V rail 5 A and 24 V rail 0.96 A, with input rated for 120/240 VAC. The 1746-P2 uses the 1746-C7 interconnect cable to link the power supply to the backplane, and Rockwell Automation notes that this model was discontinued as of September 30, 2024.
