The Allen-Bradley 1756-PB75 Series B ControlLogix® Power Supply delivers high-density, redundant power for mission-critical automation systems. Designed for Rockwell's 1756 chassis, this 75W (6A @ 5.1V DC) module supports parallel N+1 redundancy with hot-swap capability and active load balancing. Its enhanced aluminum housing withstands -40°C to +70°C extremes, 5g vibrations (IEC 60068-2-6), and 95% humidity. Integrated diagnostic LEDs monitor voltage, current imbalance (>±0.5A), and thermal status (90°C shutdown). Certified for ATEX Zone 2 and IEC 61508 SIL 2, it features conformal-coated PCBs for corrosive environments and supports generator inputs with 20ms hold-up time.
