Features:
- 90–146 V DC input for 125 V DC control-power systems
- 5 A at 5 V DC and 0.96 A at 24 V DC backplane capacity
- Separate 24 V DC, 200 mA user-power connection
The 1746-P5 powers one SLC 500 chassis from a nominal 125 V DC source while keeping the processor and module rails regulated.
Selection is a two-rail load decision: both the 5 V and 24 V demand must remain within the published limits.
Field acceptance also depends on source polarity, protection, grounding, wiring restoration, and recovery of any circuits using the user-power terminals.
The 1746-P5 Allen-Bradley may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Sum every module load separately at 5 V DC and 24 V DC.
- Include processor, communication, specialty, and local I/O modules.
- Reserve margin for the approved final chassis configuration.
- Verify 90–146 V DC at the supply terminals with correct polarity.
- Inspect branch protection, grounding, and connector seating.
- Do not bypass the chassis or supply protective devices.
- Label the input, protective-earth, and 24 V user-power conductors.
- Confirm whether external devices depend on the 200 mA user output.
- Re-energize only after enclosure and terminal checks are complete.
- SLC 500 chassis powered from nominal 125 V DC
- Legacy controller maintenance with verified module loads
- Replacement projects retaining documented SLC wiring
