Allen-Bradley 1746-P2 Power Supply Module For SLC 500 Systems

The Allen-Bradley 1746-P2 Power Supply Module is a rack‑mount power source designed for SLC 500 modular chassis, delivering the backplane rails needed by I/O modules and processors. It accepts 85–132 V AC or 170–265 V AC at 47–63 Hz and provides a typical 180 VA of line power, with outputs of 5 V DC up to 5 A (25 W) and 24 V DC up to 0.96 A for backplane/logic circuitry. Its physical size is about 5.5 in wide by 2.9 in high by 5.7 in deep, and it is intended for 0 °C to 60 °C operation; the input exhibits up to 20 A inrush current, and the unit offers 1,800 V AC isolation for 1 second. Fuse protection is provided by 1746-F1 or equivalent, and the 1746-P2 is part of the SLC 500 family of power supplies used in configurations that require higher I/O capacity than the P1 series.
