The B&R 4P3040.00-490 is a high-efficiency 24V DC Power Supply Unit engineered for B&R Automation’s X20 system, delivering reliable power distribution for industrial control cabinets in demanding automation environments. Designed for seamless integration with B&R’s modular I/O architecture, this unit converts 100-240V AC input into stabilized 24V DC output with 94% peak efficiency, minimizing heat dissipation and energy costs. The 4P3040.00-490 features active power factor correction (PFC >0.95) and comprehensive protection against overload, short-circuit, and overtemperature conditions. Its compact form factor enables space-optimized cabinet layouts, while the hot-swappable design (with redundant kits) ensures uninterrupted operation in critical applications. Compliant with global safety standards and equipped with diagnostic LEDs for real-time status monitoring, this power supply is ideal for packaging machinery, robotic cells, and process control systems requiring robust, maintenance-friendly power infrastructure.

Main Features and Advantages
Ultra-Efficient Operation: Advanced switching topology achieves 94% efficiency at full load, reducing heat generation by 30% compared to conventional supplies. Active PFC minimizes harmonic distortion.
Hot-Swap Capability: Module replacement without system shutdown when used with B&R’s redundant buffer modules (e.g., X20BB12), critical for continuous process industries.
Diagnostic Intelligence: Multi-color LED indicators provide immediate status for input voltage, output voltage, and overtemperature conditions. Remote monitoring via Automation Studio software.
Robust Design: Withstands 300V AC input surges (100ms) and operates at 70°C ambient temperature with derating. Conformal-coated PCB resists humidity and contamination.
Seamless Integration: Plug-and-play compatibility with B&R’s X20 backplanes. Automatic current balancing in parallel configurations ensures equal load sharing.
Application Field
The B&R 4P3040.00-490 powers critical automation systems:
Packaging Machinery: Supports servo drives and vision systems in high-speed filling/sealing lines
Plastics Injection Molding: Reliable power for heated barrel controls and hydraulic valve islands
Robotic Workcells: Energizes ABB/KUKA robot controllers and EOAT tooling
Printing Presses: Maintains stable voltage for web tension controls and ink systems
Energy Storage Systems: Powers BMS controllers in battery manufacturing
