Allen Bradley 1606-XLS960E-3/A Power Supply

Product Introduction

The Allen Bradley 1606-XLS960E-3/A Power Supply is a high-capacity three-phase AC/DC power supply engineered for industrial automation systems that demand reliable and stable 24V DC output at elevated power levels. As a Series A model within the 1606-XLS Performance Power family from Allen-Bradley, it combines robust electrical performance with durable construction suitable for continuous industrial operation.

Designed to operate on a 380–480V AC three-phase input, this unit efficiently converts incoming power into a regulated 24–28V DC output. With a rated output of 960W and up to 40A current, it is well suited for high-load applications such as centralized control systems, distributed I/O networks, and automation platforms requiring dependable power delivery.

The compact DIN rail mounting design allows easy integration into control cabinets, while its reinforced internal architecture ensures consistent performance under fluctuating load and environmental conditions. The Series A enhancement reflects improved stability and compatibility with modern industrial power systems.
