Main Features and Advantages
Exceptional Efficiency and Compact Design: The Allen-Bradley 1606-XLS480F achieves up to 94.3% typical efficiency through synchronous rectification technology, significantly reducing power losses and heat generation -2-3. This high efficiency allows the 1606-XLS480F to maintain its compact form factor while delivering full rated power, saving valuable panel space and reducing cooling requirements in industrial control cabinets.
150% Power Boost Capability: The 1606-XLS480F provides a short-term power boost of 150% of rated output (720W) for up to 4 seconds, enabling reliable startup of challenging loads including DC motors, capacitive loads, and equipment with high inrush current requirements -3-5. This feature allows system designers to use a lower wattage power supply than would otherwise be required, reducing both space and cost without compromising performance.
Active Power Factor Correction and Low Inrush Current: The Allen-Bradley 1606-XLS480F incorporates active power factor correction (PFC) with a typical power factor of 0.90-0.96, minimizing harmonic distortion and maximizing the usable power from the AC mains -2-3. The advanced active inrush limitation circuitry keeps inrush current below 9A peak, preventing nuisance tripping of circuit breakers and reducing stress on upstream components during power-up.
Comprehensive Diagnostic Capabilities: The 1606-XLS480F features a DC-OK relay contact and LED indicators (green DC-OK and red overload) for real-time status monitoring -3-14. The DC-OK relay provides a dry contact signal that can be integrated into control systems for remote monitoring, enabling predictive maintenance strategies and rapid fault detection.
Quick-Connect Spring Clamp Terminals: The Allen-Bradley 1606-XLS480F utilizes unique spring-clamp terminals for fast, secure, and vibration-resistant wiring connections -3-7. This termination method significantly reduces installation time compared to traditional screw terminals and ensures reliable connections in high-vibration industrial environments.
Wide Operating Temperature Range and Marine Approvals: The 1606-XLS480F operates reliably from -25°C to +70°C, with a derating of 12W/°C above 60°C -2-14. The unit holds ABS/GL/RINA marine approvals, making it suitable for shipboard and offshore applications where environmental conditions are particularly demanding -2-14.
Global Safety and Compliance Certifications: The Allen-Bradley 1606-XLS480F complies with UL 508, UL 60950-1, and Class I Division 2 hazardous location requirements, along with EMC and LVD directives, ensuring suitability for installation in virtually any industrial environment worldwide -3-5.
