Allen-Bradley 1746-P5 DC Power Supply Module – SLC 500 Series
When a power supply module fails on the plant floor, the consequences are immediate and severe. Conveyor lines halt, robotic arms freeze mid-cycle, and production supervisors scramble to identify the fault source. Every minute of unplanned downtime in a modern manufacturing facility can cost thousands of dollars in lost output, missed delivery windows, and emergency labor. The Allen-Bradley 1746-P5 DC Power Supply Module is the critical backbone that keeps your SLC 500 control system energized, stable, and running — and without it, your entire automation architecture goes dark.
Within the SLC 500 family — one of Rockwell Automation’s most enduring and widely deployed PLC platforms — the 1746-P5 occupies a specialized niche as a DC-input power supply designed for applications where AC mains power is unavailable or undesirable. It is engineered for environments that operate on 24 VDC or battery-backed DC bus systems, making it the preferred choice for mobile equipment, marine installations, remote RTU panels, and facilities with DC-dominant power infrastructure. Globally, the SLC 500 platform remains installed in tens of thousands of facilities across automotive, food & beverage, oil & gas, and discrete manufacturing sectors, and the 1746-P5 continues to be a sought-after replacement and spare part for maintaining these systems.

Always verify chassis slot compatibility and total current draw against the 1746-P5 output ratings before system commissioning.
Our Quality Assurance Process
- Source Verification: All units are sourced from authorized distributors, certified resellers, or directly from controlled surplus channels with documented provenance.
- Visual & Physical Inspection: Each module is inspected for physical damage, label integrity, connector condition, and signs of prior field use or repair.
- Functional Testing: Where applicable, modules undergo power-on and functional verification prior to shipment.
- Anti-Counterfeit Screening: We apply multi-point checks against known counterfeit indicators for high-demand Rockwell Automation part numbers.
- Secure Packaging: ESD-safe packaging with moisture barrier protection for international shipment.

Frequently Asked Questions
Q: Is the 1746-P5 still in production by Rockwell Automation?
A: The SLC 500 platform has been in a mature/end-of-life phase. Rockwell Automation has encouraged migration to newer platforms such as the CompactLogix (1769) series. However, the 1746-P5 remains available as a spare and surplus part through specialized distributors like Konmask.com to support existing installed systems.
Q: What is the input voltage range of the 1746-P5?
A: The specific DC input voltage range should be confirmed from the official Rockwell Automation product bulletin or datasheet for the 1746-P5. Please contact us and we can provide the technical documentation along with your quote.
Q: Can the 1746-P5 replace other 1746-P series power supplies?
A: The 1746-P series includes multiple models (P1, P2, P3, P4, P5, P6, P7) with different input types and output ratings. The P5 is specifically a DC-input model and is not a direct drop-in replacement for AC-input variants. Always verify the input type and output current capacity before substituting power supply modules.
Q: Do you provide a warranty on the 1746-P5?
A: Yes. We offer a standard warranty on all units shipped. Warranty terms are confirmed at the time of quotation. Please contact us for details.
Q: How long does international shipping take?
A: Typical international express delivery (DHL/FedEx/UPS) takes 3–7 business days depending on destination country and customs clearance. We provide full tracking information upon shipment.
