Allen-Bradley 1606-XLE120E-2 Power Supply

Allen-Bradley 1606-XLE120E-2 Power Supply Overview

The 1606-XLE120E-2 belongs to the Allen-Bradley Bulletin 1606-XL Essential series. This switched-mode power supply delivers 24V DC output with 120W rated power. Panel builders pick it for machines wired to two-line 380-480V AC feeds. The unit connects across L1 and L2, so no neutral conductor is required. Furthermore, its output stays adjustable from 24 to 28V DC to match field device needs. A DC OK relay contact provides a simple status signal for monitoring. Therefore, maintenance teams can detect supply faults without extra hardware. Screw terminals deliver secure, familiar wiring for service technicians. Besides, an active inrush current limiter reduces startup stress on upstream breakers. A dynamic 120% power boost supports brief load peaks under +45°C. In short, the 1606-XLE120E-2 combines two-line input convenience with solid protection and easy installation.

Key Technical Specifications

First, the input stage accepts 380 to 480V AC nominal across two lines at 50/60 Hz. The nameplate marks the input as 2AC 380-480V, and rated operation sits at 380V AC. Next, the output provides 24V DC nominal and stays adjustable from 24 to 28V DC. Output current reaches 5A maximum, which yields 120W rated power. It falls to about 4.3A at the upper temperature range. Moreover, typical efficiency reaches 90.4%, and power losses sit near 12.7W typical. The power factor measures 0.45 typical, and inrush current reaches 4A/4A typical. Additionally, an active inrush current limiter protects upstream protection devices. Input circuit protection calls for a 6A slow-blow fuse, with an external fuse of min B-6A or C-3A. Finally, the unit carries UL 60950-1, cUL, and CE marks under the Bulletin 1606 standard.

Communication and Signaling

The 1606-XLE120E-2 has no built-in communication ports or protocols. Instead, a DC OK relay contact delivers a dry status signal. This contact suits PLC digital inputs, alarm lamps, or panel indicators. For instance, wire the relay to a controller input to flag supply faults. Consequently, commissioning stays simple and costs remain low. If you need fieldbus diagnostics, add an external monitoring module. Otherwise, the relay contact covers most basic status needs.

Mechanical and Environmental Data

The housing measures 124 × 40 × 117 mm and weighs 0.50 kg. It carries an IP20 protection rating, so it suits protected cabinet interiors. Operating temperature spans -25 to +70°C, with output current derating at the top end. Storage temperature starts at -25°C as the published lower bound. Humidity tolerance reaches 5 to 95% for indoor environments. The 40mm width saves valuable DIN rail space in crowded panels. Besides, wall mounting holes offer layout flexibility when rail space runs short.

Installation Guide

Begin by snapping the unit onto a 35mm DIN rail or fastening it to a wall. Next, wire the two-line input to terminals L1 and L2 and fit the recommended external fuse. Then, set the output voltage between 24 and 28V DC to match your load. After that, wire the DC OK relay contact to your monitoring circuit. Ensure adequate ventilation around the housing during operation. Finally, verify the output with a meter before energizing downstream equipment. The 1606-XLE120E-2 ships as an active product with full Rockwell support.
