It delivers 5 V DC at up to 2 A, supporting the SLC 500 backplane with two input voltage ranges: 85–132 V AC or 170–265 V AC (accommodating both 120 V and 240 V mains) and an operating frequency around 47–63 Hz. This model is the entry-level power supply in the 1746-P family, commonly used in discrete manufacturing and process automation applications where a compact, rack-mounted 5 V supply is required. Higher-current alternatives in the same family—1746-P2, 1746-P3, 1746-P4, and 1746-P5—offer increased output capability for larger I\/O loads. In SLC 500 systems, the 1746-P1 typically powers the I\/O racks and related peripherals, contributing to stable, reliable operation of the modular control system. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51658965483822,"sku":null,"price":72.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ed328ff7-9610-4612-aa93-97e869feca87.jpg?v=1769526100","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-p1-slc-500-plc-power-supply","provider":"PLG Automation ","version":"1.0","type":"link"}
