The Allen-Bradley 1756-PB72/B ControlLogix® Power Supply delivers 72W (3A @ 24V DC) of high-efficiency power for mission-critical automation systems. Designed for the 1756 chassis platform, this dual-slot module features:
- N+1 redundancy support
- Hot-swap capability
- Active current-sharing technology
Its rugged aluminum housing (-40°C to +70°C operating range) withstands 5g vibrations (IEC 60068-2-6), 95% humidity, and corrosive environments. Integrated diagnostic LEDs monitor voltage stability, load distribution, and thermal status, while conformal-coated PCBs provide exceptional resistance to dust, chemicals, and condensation. Certified for ATEX Zone 2 and IEC 61508 SIL 2, it's ideal for hazardous locations.
