It accepts a universal AC input of 85–132 VAC or 170–265 VAC at 47–63 Hz, with a typical line power of about 135 VA and an inrush up to 20 A, and it uses 1746-F1 (or equivalent) fuse protection. Internally, the unit provides 5 V DC at up to 2 A to the 5 V\/backplane circuitry and 24 V DC with an internal capability of 0.46 A, while offering a separate 24 V user-power rail up to 200 mA and a user-power voltage range of 18–30 V DC (typical 20.4–27.6 V). The 1746-P1 features 1800 V AC RMS isolation for 1 second (with corresponding DC isolation ratings) between primary and secondary, and it is rated for ambient operating temperatures from 0 to 60 °C with a 5% derating above 55 °C. Wiring guidance specifies #14 AWG is appropriate for connections, consistent with SLC 500 installation practices. This rack-mount power supply is designed specifically for the SLC 500 family (Bulletin 1746) to power both the backplane and user peripherals within a single chassis, supporting reliable operation of I\/O modules and the controller in typical industrial environments.\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51659708793134,"sku":null,"price":1305.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_e6db77f0-ebd7-4147-bcc6-40a5af12bb81.jpg?v=1769529772","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-p1-rack-mount-power-supply","provider":"PLG Automation ","version":"1.0","type":"link"}
