Allen-Bradley 1746-P2 Power Supply Module

Allen-Bradley 1746-P2 Power Supply Module is a rack-mount DC power supply for the SLC 500 system, designed to live in SLC chassis and power the backplane and I/O modules. It accepts line voltage in the 85–130 VAC or 170–265 VAC range (typical 120/240 V) with a line frequency of 47–63 Hz and an approximate input power of 70 W. The module provides a regulated DC output in the 18–30 V range (nominally 24 V DC) to the backplane, with backplane current specifications cited as up to 5 A on the 5 V rail and about 0.96 A on the 24 V rail. With dimensions about 5.5 inches wide, 2.9 inches high, and 5.7 inches deep, it is intended for rack-mount installation in SLC 500 configurations. Operating temperature tolerance is 0 to 60 °C. The 1746-P2 is used to reliably power Allen‑Bradley SLC 500 processors and I/O cards within compatible rack assemblies, delivering stable DC power essential for PLC logic and field devices.
