Allen-Bradley 1606-XLE240E-3 Power Supply

Allen-Bradley 1606-XLE240E-3 Power Supply Overview

The 1606-XLE240E-3 belongs to the Allen-Bradley Bulletin 1606-XL Essential series. This switched-mode power supply delivers 24V DC output with 240W rated power. Panel builders pick it for machine control, pump stations, and three-phase automation cabinets. The unit accepts three-phase AC input from 380 to 480V AC nominal. 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, a dynamic 120% power boost supports startup currents at up to +45°C. This burst helps during motor startup or capacitor charging. In short, the 1606-XLE240E-3 combines three-phase input, solid protection, and straightforward installation.

Key Technical Specifications

First, the input stage accepts 380 to 480V AC three-phase nominal for industrial distribution systems. Next, the output provides 24V DC nominal and stays adjustable from 24 to 28V DC. Output current reaches 10A maximum, which yields 240W rated power. Moreover, typical efficiency reaches 92.8%, which keeps heat loss manageable inside enclosures. Additionally, a dynamic 120% power boost handles short load peaks at up to +45°C. This feature supports contactor coils and capacitive loads during energizing. Protection covers overload and short-circuit events per series design. Finally, the unit carries UL 60950-1, cUL, and CE marks under the Bulletin 1606 standard.

Communication and Signaling

The 1606-XLE240E-3 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 × 62 × 117 mm and weighs 0.75 kg. It carries an IP20 protection rating, so it suits protected cabinet interiors. Operating temperature spans -25 to +70°C for continuous duty. Storage temperature starts at -25°C as the published lower bound. Humidity tolerance reaches 5 to 95% for indoor environments. The 62mm width supports heat dissipation for three-phase operation. Besides, wall mounting holes offer layout flexibility when DIN rail space runs short.

Installation Guide

Begin by snapping the unit onto a 35mm DIN rail or fastening it to a wall. Next, strip the three-phase input wires and secure them in the screw terminals. 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-XLE240E-3 ships as an active product with full Rockwell support.
