Allen Bradley 1606-XLS480F-3 Power Supply

Product Introduction

The Allen Bradley 1606-XLS480F-3 Power Supply is a high-efficiency three-phase AC/DC power supply designed for industrial systems that require reliable and stable 48V DC power. As part of the 1606-XLS Series Performance Power portfolio from Allen-Bradley, this model is engineered to support demanding automation and process control environments.

With a wide three-phase AC input range of 380–480V AC, the unit converts incoming power into a regulated 48–56V DC output. Delivering up to 480W and 10A output current, it is particularly suited for applications requiring higher DC voltage levels, such as industrial networking, drives, and control systems.

The compact housing combined with DIN rail mounting and spring-clamp terminals ensures quick installation and secure wiring. Its robust internal design, high efficiency, and fanless cooling concept make it suitable for continuous operation in harsh industrial conditions.
