Allen-Bradley 1606-XL480EPT: 480W DIN Rail Mount Power Supply Unit

Technical Specifications

Main Features and Advantages

The Allen-Bradley 1606-XL480EPT​ distinguishes itself with features designed for maximum system availability and ease of use. Its most prominent advantage is the integrated buffering capability. The included Energy Pack provides ride-through during short AC line interruptions, which are common in industrial environments. This ensures that critical control processes are not interrupted by minor grid fluctuations, preventing nuisance shutdowns, data loss, and costly production halts. Combined with its wide-range input voltage (120-240V AC auto-select), the power supply is highly adaptable to different electrical infrastructures globally and tolerant of line voltage variations.High efficiency and active Power Factor Correction (PFC) are key performance benefits. An efficiency rating over 90% means less wasted energy is dissipated as heat, reducing the thermal load on the control panel and allowing for higher ambient operating temperatures or smaller enclosures. Active PEC brings the input current waveform in phase with the voltage, reducing harmonic feedback into the AC line. This not only meets stringent power quality standards but also allows for the use of smaller upstream breakers and wiring. The Allen-Bradley 1606-XL480EPT​ is built for durability in harsh conditions, with a wide operating temperature range and conformal coated printed circuit boards for protection against humidity, dust, and corrosive atmospheres. Diagnostic capabilities are enhanced through clear LED status indicators for power, output, and buffer health, enabling quick visual troubleshooting. Its modular, plug-and-play design on the DIN rail simplifies installation, maintenance, and potential expansion. The robust electrical design includes comprehensive protection against overloads, short circuits, and overtemperature, safeguarding both the power supply itself and the sensitive downstream control equipment it powers. This combination of reliability, intelligence, and protection makes the 1606-XL480EPT​ a premium choice for mission-critical industrial power distribution.

Application Field

The Allen-Bradley 1606-XL480EPT​ is deployed across virtually all manufacturing and process industries as the primary 24V DC power source for control systems. In automotive manufacturing, it powers the PLCs, safety controllers, and I/O racks that control robotic welding cells, painting lines, and final assembly conveyors, where a power interruption could halt an entire production line. In food and beverage processing, the clean, stable power from the 1606-XL480EPT​ is essential for the precise control of batching systems, fillers, and packaging machines, and its robust design can withstand washdown environments. The integrated ride-through is particularly valuable in these continuous processes.For material handling and logistics, such as in automated storage and retrieval systems (AS/RS) or sortation centers, this power supply ensures that the control logic for motors, scanners, and diverters remains active during the brief voltage sags that can occur when large motors elsewhere in the facility start. In the water/wastewater and oil & gas sectors, where reliability is paramount for public safety and environmental protection, the Allen-Bradley 1606-XL480EPT​ provides dependable power for remote telemetry units (RTUs), pump control panels, and valve actuators, often in outdoor or harsh environments. It is also the ideal choice for OEM machinery builders, providing a standardized, high-quality power solution for complex machines like printing presses, plastic injection molders, and metal forming equipment. Any application that utilizes Allen-Bradley Logix, CompactLogix, GuardLogix, Point I/O, or other industrial control components, and requires a robust, centralized 24VDC power source with high availability features, is a prime application for the Allen-Bradley 1606-XL480EPT​ power supply unit.
