1769-PA4 CompactLogix Selectable AC Power Supply 4A/2A | Allen-Bradley

The Original New Allen-Bradley 1769-PA4 CompactLogix Selectable AC Power Supply is a high-performance power module designed to provide reliable power distribution for CompactLogix™ 1769-L3x controllers and I/O systems. This expansion power supply unit converts 120/240V AC input to 5V DC and 24V DC outputs, delivering 4A at 5V DC and 2A at 24V DC. Featuring a switch-selectable input voltage range (85-132V AC or 170-265V AC), it supports global industrial applications and provides the necessary power for up to eight I/O modules on each side of the power supply. Ideal for small to mid-size applications requiring reliable power distribution in CompactLogix automation systems.
