1606-XLS480EE 24V Performance Power Supply Allen-Bradley

Allen-Bradley 1606-XLS480EE Performance Power Supply

Product Introduction

The 1606-XLS480EE belongs to the Allen-Bradley Bulletin 1606-XL performance series. It targets panel builders who work with 200...240 V AC mains. This variant removes the wide-range input stage, which raises efficiency to 94.5% typical. Consequently, the unit runs cooler and consumes less energy in continuous operation.

This model delivers a regulated 24V DC output at 20A. Specifically, it provides 480W of rated power with a 50% power reserve. The reserve supports short-term peak loads from motors, valves, and capacitive circuits. Furthermore, spring terminals simplify wiring and resist vibration. Engineers often choose this supply for compact cabinets where heat and space are limited.

Technical Specifications

Electrical Parameters

The 1606-XLS480EE accepts AC 200...240 V nominal input. It does not include the wide-range stage, so it suits regions with stable 230 V mains. The output voltage is nominally DC 24 V, adjustable from 24 to 28 V. Additionally, the unit supplies 20 A nominal current, ranging from 20 to 17.7 A across the adjustment band.

Efficiency reaches 94.5% typical at full load. Ripple and noise stay at 100 mV maximum. Moreover, the 50% power reserve enables reliable startup of inductive loads. The DC OK relay contact provides a dry signal for output status monitoring. Therefore, control systems can detect voltage faults within milliseconds.

Mechanical and Environmental Data

The housing measures 124 mm in height, 70 mm in width, and 127 mm in depth. It weighs approximately 880 g. The 1606-XLS480EE uses spring terminals, which accept solid and stranded wires without screws. This design reduces installation time and improves vibration resistance.

Operating temperature spans -25 to +70 °C. Storage temperature ranges from -40 to +85 °C. Relative humidity tolerance is 5 to 95%, non-condensing. The protection rating is IP20 for enclosed cabinet mounting. Besides, the narrow 70 mm width saves DIN rail space in crowded enclosures.

Installation Guide

First, snap the 1606-XLS480EE onto a standard 35 mm DIN rail. Verify that the rail clip locks firmly into place. Next, strip the input wires and insert them into the spring terminals. Push the lever or insert the wire directly, depending on the terminal style. The 200...240 V input suits most European and Asian industrial mains.

After the input connection, wire the 24V DC output to the load. Confirm polarity before energizing the unit. Then, adjust the output voltage using the front potentiometer if the application requires 28 V. Finally, connect the DC OK relay to a monitoring input. This step lets the controller receive a fault signal quickly.

FAQ

Q1: How does the 1606-XLS480EE differ from the wide-range XLS models?
A1: This variant accepts only AC 200...240 V input. It omits the wide-range input stage, which raises efficiency to 94.5%. Therefore, it suits stable 230 V mains environments.

Q2: How much power reserve does this supply offer?
A2: The 1606-XLS480EE provides a 50% power reserve. This means it can deliver up to 720W for short periods. Consequently, it handles high inrush currents from motors and capacitive loads.

Q3: What type of terminals does this power supply use?
A3: It uses spring terminals instead of screw terminals. Spring terminals accept wires quickly and resist vibration loosening. As a result, wiring time drops and long-term reliability improves.

Q4: What are the dimensions and weight of the 1606-XLS480EE?
A4: The unit measures 124 mm (H) x 70 mm (W) x 127 mm (D). It weighs approximately 880 g. The 70 mm width fits compact DIN rail layouts in industrial cabinets.

Q5: Does the 1606-XLS480EE include communication ports?
A5: No, this is a standalone power supply without communication interfaces. It provides a DC OK relay contact for basic status monitoring. The relay signals whether the output voltage is within the correct range.
