The Allen-Bradley 1756-PBXT/B Power Supply is a high-capacity, redundant AC/DC power module engineered for Rockwell Automation's ControlLogix® systems in mission-critical industrial applications. Designed with dual-input redundancy (100-240V AC ±10%, 47-63Hz), this hot-swappable unit delivers 10A continuous load at 5.1V DC to power ControlLogix chassis, including processors and I/O modules.
Featuring auto-ranging voltage detection and PowerFlex™ technology, it maintains ±1% voltage regulation during brownouts (down to 85V AC) and supports seamless transfer between main/backup sources. The rugged enclosure meets NEMA Type 12/4X/13 standards with -40°C to +70°C operation and includes diagnostic LEDs for phase loss, overload, and thermal fault alerts.
- Input Voltage: 100-240V AC (auto-sensing) / 85-264V DC (optional)
- Output: Isolated 5.1V DC @ 10A continuous (60W) / 13A peak (5s)
- Efficiency: 88% typical (Energy Star Level VI compliant)
- Protections: Full-brick redundancy + short-circuit/overvoltage/overcurrent safeties
- Hold-up Time: 20ms @ full load during power interruption
- Inrush Current: <45A (NTC-limited)
- Isolation: 3000V AC input-to-output / 1500V AC input-to-ground
- Certifications: UL 61010-1, ATEX Cat 3 Zone 2, CE, cULus, RoHS
- Harmonics: <10% THDi (EN 61000-3-2 Class A)
- Energy SCADA Systems: Uninterrupted PLC control in substations during grid fluctuations
- Automotive Production: Robotic assembly line chassis power redundancy
- Chemical Plants: Batch reactor control systems requiring SIL 2 compliance
- Water Treatment: Pump station control cabinets exposed to humidity
- Food Processing: Washdown-rated environments (IP65 with optional kit)
- Pharmaceutical: Cleanroom manufacturing with EMI-sensitive equipment
- Data Centers: Industrial-grade UPS bridging for critical automation
