Allen-Bradley 1606-XLS240-UPS DC-UPS Module

Allen-Bradley 1606-XLS240-UPS DC-UPS Module

Product Introduction

The 1606-XLS240-UPS belongs to the Allen-Bradley Bulletin 1606-XL family. This DC-UPS module works in bridge operation with a 1606-XLS power supply. Specifically, it maintains the 24 V DC bus during mains failures by drawing energy from an external 12 V battery. Engineers deploy this unit where short power interruptions must not stop control systems, PLC racks, or safety circuits.

Technical Specifications

The input accepts a 22.5…30 V DC bus from the connected power supply. Meanwhile, the output stays within the same 22.5…30 V DC range. In buffer mode, the module regulates the output to 22.5 V to protect connected loads. The rated output power reaches 240 W, and normal-mode output rises to 360 W.

Current ratings depend on the operating mode. Output 1 carries 15 A in normal mode, while buffer mode allows 10 A continuous or 15 A peak. Additionally, the module draws 1.3 A internally, including charging current. Therefore, size the upstream supply with this extra load in mind.

Battery selection ranges from 3.9 Ah to 40 Ah at 12 V nominal. The battery is ordered separately, so runtime depends on your chosen capacity. Charging time and buffer time are not published values because they vary with battery size. For instance, a 40 Ah battery supports much longer backup than a 3.9 Ah unit. Consequently, match battery capacity to your required holdup window.

This module includes no communication ports or fieldbus protocols. However, status LEDs on the front panel indicate operating and buffer states. Protection features include reverse polarity protection and overload limiting.

Mechanical and Environmental Parameters

The housing measures 124 mm in height, 49 mm in width, and 117 mm in depth. Furthermore, the unit weighs only 530 g, so it adds little load to the DIN rail. Operating temperature ranges from -25 to +70 °C according to Rockwell technical data. The IP20 rating suits open-frame cabinet installation. Humidity tolerance spans 5 to 95 percent non-condensing.

Installation Guide

First, mount the module on a DIN rail next to the 1606-XLS power supply. Next, wire the supply output to the module input using the screw terminals. Then connect the external 12 V battery to the dedicated battery terminals, observing polarity. Additionally, keep battery cables short to reduce voltage drop. Verify the battery voltage matches the 12 V nominal requirement before connection. Finally, confirm the buffer LED lights during a simulated mains failure test.
