Allen-Bradley 1746-P3 SLC 500 Power Supply Module

The Allen-Bradley 1746-P3 SLC 500 Power Supply Module provides regulated DC power to the SLC 500 PLC rack and I/O modules, delivering typical 5 V and 24 V DC for logic and field power. This rack-mounted power module fits Allen-Bradley SLC 500 PLC and I/O racks and accepts AC mains input (verify specific voltage rating before installation), with model-dependent output current and power rating to meet industrial control needs. It mounts in the SLC 500 chassis and supplies regulated DC power to the PLC processor and I/O modules, enabling dependable operation across manufacturing lines, material handling, process control facilities, water and wastewater plants, and packaging machinery. Protection features include overload and short-circuit protection (model dependent) under industrial-rated operating temperatures. Common replacements include Allen-Bradley 1746-P5, 1746-P32, and the 1606-XLS480E AC/DC Power Supply.
