The Allen-Bradley 1756-PA72/C ControlLogix® Power Supply is a high-performance, dual-slot module delivering 72W (3A @ 24V DC) of stable power for mission-critical automation systems. Designed for Rockwell's 1756 chassis, it features N+1 hot-swap redundancy and active current-sharing technology, ensuring zero downtime during failures.
Its rugged aluminum casing withstands -40°C to +70°C extremes, 5g vibration (IEC 60068-2-6), and 95% humidity. Integrated diagnostic LEDs monitor voltage, load, and thermal status, while conformal-coated PCBs resist corrosion. Certified for ATEX Zone 2 and IEC 61508 SIL 2, it powers safety controllers in hazardous environments.
