Allen-Bradley 1768-PB3 CompactLogix Power Supply

The Allen-Bradley 1768-PB3 CompactLogix Power Supply provides regulated 24V DC power to CompactLogix PLC systems, supplying processors and associated modules with stable voltage. With a 24V DC input, it is designed for panel-mounted or DIN-rail installation (system dependent) and includes overload and short-circuit protection to support reliable PLC operation. Used in industrial automation panels, machine control systems, and production lines, this power supply distributes power to CompactLogix controllers, I/O modules, and communications interfaces in applications such as conveyors, packaging machines, assembly lines, and process control. Common replacements include Allen-Bradley 1768-PA3, 1768-PB2, and 1769-PB4.
