Allen-Bradley 1606-XLS960E-3 Power Supply

Allen-Bradley 1606-XLS960E-3 Power Supply

Product Introduction

The 1606-XLS960E-3 belongs to the Allen-Bradley Bulletin 1606-XL Performance family. This switched-mode power supply converts three-phase AC input into a regulated 24 V DC output. Specifically, it provides 960 W of continuous power with a 40 A maximum output current. Engineers choose this unit for high-demand industrial panels requiring reliable DC power.

Technical Specifications

The input voltage range spans 380…480 V AC for three-phase nominal operation. Meanwhile, the output voltage remains adjustable from 24…28 V DC. This flexibility supports sensitive loads and battery charging circuits. The unit achieves 95.3% typical efficiency, which reduces heat generation inside enclosures. Additionally, a 20 ms hold-up time maintains output during brief input interruptions.

A key feature is the reserve power function, often called BonusPower. The 1606-XLS960E-3 delivers a 60 A boost for up to four seconds. For instance, this capability easily handles motor start-up loads and capacitive inrush currents. Consequently, you may select a smaller power supply for applications with temporary peak demands.

The DC OK relay contact provides a simple status signal. However, this model includes no communication ports or fieldbus protocols. Therefore, it suits systems where basic monitoring is sufficient. Protection features include short-circuit proofing and active inrush current limiting.

Mechanical and Environmental Parameters

The housing measures 124 mm in height, 110 mm in width, and 127 mm in depth. Furthermore, the unit weighs approximately 1.50 kg. The IP20 protection rating guards against finger contact and solid objects above 12.5 mm. Operating temperature ranges from -25 °C to +70 °C with derating above 60 °C. Storage temperature extends from -40 °C to +85 °C.

Installation Guide

First, verify the input supply matches the 380…480 V AC three-phase rating. Next, mount the unit either on a DIN rail or directly to a wall using the provided hardware. Use screw terminals for all input and output connections. Additionally, install a 6 A slow-blow fuse on the input circuit for protection. Ensure adequate ventilation clearance around the housing. Finally, adjust the output voltage potentiometer to the desired setpoint between 24 V and 28 V DC before connecting sensitive loads.
