Main Features and Advantages
Power Boost for real-world loads: The headline capability of the Allen-Bradley 1606-XLS480F is its ability to deliver 150 % of rated output — 15 A at 48 V — for typically four seconds, repeatably, under hardware control rather than as a thermal exception. This directly addresses the most common sizing error in panel design: specifying a supply twice as large as needed simply to survive contactor inrush, solenoid switching or capacitive charging. With 1606-XLS480F, a 480 W unit handles load peaks that would otherwise force a 720 W or 960 W selection, saving both rail space and cost.High efficiency with low heat: At 94.3 % efficiency and 29 W of losses at 230 V AC, the Allen-Bradley 1606-XLS480F puts far less heat into the enclosure than a conventional design of the same rating. That matters more than the energy bill: in a sealed control cabinet, every watt of loss raises internal temperature and shortens the life of every other component in the panel. Combined with a −25 °C to +70 °C operating range and controlled derating of 12 W/°C above 60 °C, the supply remains predictable in hot installations.Diagnostics built in: A DC-OK relay contact allows the 1606-XLS480F to signal output health directly to a PLC input or an alarm circuit, while the green DC-OK and red overload LEDs give a technician an instant status read at the panel. On overload the unit drops into a controlled current-limiting mode and, if the output voltage collapses below roughly 40 V, enters hiccup mode with periodic restart attempts — protecting both itself and the load rather than latching off or failing destructively.Installation speed and global acceptance: Quick-connect spring-clamp terminals make wiring fast and vibration-resistant without ferrule crimping, the compact 82 mm width allows dense side-by-side mounting, and the unit carries broad international approvals including ABS, GL and RINA marine certification — making 1606-XLS480F a single catalogue number that can be standardised across land-based and marine projects.Input flexibility: Wide-range 100–240 V AC input plus 110–300 V DC input means one model covers global AC supplies and DC bus installations, while active PFC and an active inrush limiter keep the supply friendly to generators, UPS systems and neighbouring devices on the same feeder.
