Allen-Bradley 1769-PA2 Power Supply Module CompactLogix

Allen-Bradley 1769-PA2 CompactLogix AC Power Supply Module, Revision 3 (C10), provides the essential dual rails to power CompactLogix backplanes and I/O in 1769-L3x–based systems. It accepts a wide-range AC input from 85 to 265 VAC (47–63 Hz) with nominal operation at 120/240 VAC, and delivers +5 VDC at up to 2 A and +24 VDC at up to 0.8 A to the backplane and connected I/O. Expect a maximum load of 100 VA at 120 VAC or 130 VA at 240 VAC, with inrush currents listed as up to 25 A at 132 VAC and 40 A at 265 VAC. The PA2 uses a front-access fuse for protection, with typical replacement options including Wickmann parts such as 19195-3.15A, 19343-1.6A, or 19181-4A. No jumpers or DIP switches are required for operation, and the module is designed for use in standard 1769 Compact I/O racks with 1769-L3x controllers, delivering reliable, isolated 5 V and 24 V rails to support the system’s logic, I/O, and peripheral devices.
