The Allen-Bradley 1756-PB75/B ControlLogix® Power Supply is a high-capacity, redundant power module engineered for mission-critical automation systems. Designed for Rockwell’s 1756 chassis, it delivers 75W (6A @ 5.1V DC) with N+1 hot-swap redundancy, ensuring zero downtime during failures. Its rugged die-cast aluminum housing features IP54 protection (–40°C to +70°C) and withstands severe shock/vibration (15g IEC 60068-2-27). Integrated dual-input auto-ranging (100–240V AC ±10%, 47–63Hz or 125–250V DC) enables global deployment. Key innovations include active harmonic filtering (<8% THDi), predictive failure alerts, and Studio 5000® integration for real-time health monitoring.
