Allen-Bradley 1746-P2 Slot Rack And Power Supply

Allen‑Bradley 1746‑P2 is a rack‑mount power supply for SLC 500 systems that installs in the leftmost slot of a 1746 chassis (for example the 1746‑A4 4‑slot rack) to power the backplane and local 24 V loads. It accepts 120/240 VAC input at 47–63 Hz and is protected by a 3 A, 250 V fuse. The unit provides a 5 V DC backplane output at 5 A and a 24 V DC user output rated up to approximately 0.96 A, with the user side specified for 18–30 V DC operation. Dimensions are about 140 × 74 × 145 mm and weight around 1.1 kg, making it a compact, serviceable component in SLC 500 installations. Common applications include powering the SLC backplane and supplying 24 V for nearby I/O devices and small peripheral modules within industrial control panels that use a 1746 rack.
