The Allen-Bradley 1746-P2 SLC 500 power supply is a rack‑mount module that accepts line voltage in the 85–132 VAC or 170–265 VAC range (47–63 Hz) and provides three DC outputs to power the backplane and I/O: 5 VDC at up to 5 A for logic/backplane, 24 VDC at 0.96 A for backplane, and a separate 24 VDC user rail at 0.2 A. Typical line power is 180 VA with a maximum inrush current of 20 A. The unit’s internal current capacity aligns with these outputs (5 A at 5 VDC and 0.96 A at 24 VDC), and it is fused via 1746-F2 (or equivalent) on the supply path. Physical dimensions are approximately 6 × 6 × 3.5 inches and it weighs about 1.35 lb, making it a compact power solution for 1746‑series racks.
