Allen-Bradley 1606-XLE480EP 480W Power Supply

Product Introduction

The 1606-XLE480EP sits in the Allen-Bradley Bulletin 1606-XL Essential family of switched-mode power supplies. This model converts single-phase 120 or 240 V AC into a regulated 24 V DC rail for industrial control loads. Specifically, it supplies up to 20 A and reaches a rated power of 480 W. Power factor correction comes built in, and typical efficiency reaches 95.6%, which reduces heat inside enclosures. Moreover, a DC OK relay contact gives technicians a simple status signal without any communication bus. The product remains active on the official Rockwell product page, so new builds and spare-part plans can both rely on it.

Technical Specifications

The electrical design of the 1606-XLE480EP focuses on high output current from a standard single-phase feed. Input voltage accepts 120 or 240 V AC nominal. The output is 24 V DC nominal and stays adjustable across 24–28 V DC. At 24 V, the unit delivers 20 A maximum, which gives the full 480 W rating. Efficiency is 95.6% typical, and power factor correction keeps input harmonics low.

Boost and Signaling Behavior

A dynamic 120% power boost is available up to +45 °C. Therefore, the supply can briefly push about 24 A for motor starts or capacitive loads. Meanwhile, the DC OK relay contact reports output status to a PLC or indicator lamp. The unit has no communication ports and no protocols; the relay contact is the only signal path. Screw terminals handle all input, output, and signal wiring.

Mechanical and Environmental Parameters

The body measures 124 mm high, 48 mm wide, and 127 mm deep, and it weighs 0.83 kg. DIN rail and wall mounting are both supported, which adds layout flexibility. The open-frame design carries an IP20 rating, so it belongs inside a protective enclosure. Operating temperature spans -25 to +70 °C, and relative humidity runs 5 to 95%. The published storage lower bound is -25 °C; the full storage range is not listed numerically. Approvals include UL 60950-1, cUL, and CE marking.

Thermal and Derating Notes

High efficiency lowers internal heat, yet the 120% boost applies only up to +45 °C. Above that point, available output power derates with ambient temperature. Consequently, installers should leave clearance above and below the unit for convection. Wall mounting can help when panel airflow is limited. In addition, keep the DC OK relay wiring separated from power cables to avoid false signals.

Installation Guide

First, confirm that the mains supply matches 120 or 240 V AC nominal. Next, mount the 1606-XLE480EP on a DIN rail or a flat wall surface inside the enclosure. After that, connect input, output, and relay terminals with the screw terminals, observing polarity. Then set the output voltage within 24–28 V DC using the front adjustment. Finally, apply power and check the DC OK contact state. Leave ventilation clearance, and tighten terminals to the torque stated in the manual. Route signal wires away from noisy power lines throughout the panel.

FAQ

Q1: What makes the 1606-XLE480EP different from standard 1606-XL units?
The Essential series adds power factor correction and higher efficiency. This model reaches 95.6% typical efficiency and delivers 480 W from a single-phase input, while many standard units need three phases for similar power.

Q2: How long can the 120% power boost last?
The dynamic boost of about 24 A is available up to +45 °C ambient. Above that temperature, output power derates. Use the boost for short startup peaks, not for continuous loads.

Q3: Does the 1606-XLE480EP support communication protocols?
No. It has no communication ports and no protocols. The DC OK relay contact is the only status output, and it works as a dry signal for PLCs or lamps.

Q4: Can I adjust the output above 24 V?
Yes. The output is adjustable from 24 to 28 V DC. At higher voltage settings, the maximum current stays capped, so available wattage remains within the 480 W rating.

Q5: What mounting options does this supply offer?
It supports both DIN rail and wall mounting. This flexibility helps when panel depth or airflow favors a flat mounting position instead of a rail.
