What is the Allen-Bradley 1746-P2?
Rockwell Automation publishes 1746-P2 as the SLC Rack Mounting Power Supply within the 1746 SLC 500 system, and its cut sheet gives the rating as 120/240V AC, 5A. Rockwell also lists the product as discontinued, announcing that it is no longer available for sale as of September 30, 2024. Anything beyond that — rack, processor, or module compatibility for your specific system — should be confirmed against your own documentation and with the supplier.

Common formatting variations
Suppliers, ERP records, and handwritten work orders do not always write the number the same way. These are the forms worth trying — or ruling out — when a search returns nothing:
- 1746-P2 (as printed by Allen-Bradley)
- 1746P2 — hyphen dropped in ERP records and spreadsheets
- AB 1746-P2 or Allen-Bradley 1746-P2 — brand prefixed by suppliers
- 1746-P1, 1746-P3, 1746-P4 — different power supplies in the same family, not this part
Why teams search for 1746-P2 replacements
Older SLC 500 systems continue to run in many plants, and the power supply is often the first component teams look at when a chassis stops powering on. Because the part is discontinued, remaining supply is spread across distributor stock, surplus, and repair or exchange services, which makes comparing several suppliers in one pass worthwhile.
Search the exact part number
Searching "SLC 500 power supply" is less precise than searching "1746-P2". Other supplies in the same family — 1746-P1, 1746-P3, 1746-P4 — carry different ratings, and condition and listing formats vary by supplier. The exact catalog number narrows results to listings that actually match the part you need.
How to read the listing types you may see
New
Factory-new remaining stock from an industrial distributor or reseller.
Used
Previously installed units — condition and testing vary by seller.
Surplus
Unused inventory from closed lines or overstock, often with limited warranty.
Refurbished
Inspected, cleaned, and tested units, sometimes with a limited warranty.
Repaired
A failed unit returned to working order by a repair service.
Repair service
Send-in service to repair your existing failed unit.
Exchange

Request a quote
Some suppliers hide pricing and ask you to enquire before ordering.
Out of stock / backorder
Listed but not on the shelf — ask for a firm lead time before committing.
Supplier prices and availability may change between your search and your order. Confirm condition, package quantity, stock, and lead time directly with the supplier before purchasing.
