Allen-Bradley 1606-XLS480E-3C Power Supply

Allen-Bradley 1606-XLS480E-3C 480W Three-Phase Power Supply

Product Introduction

The 1606-XLS480E-3C belongs to the Allen-Bradley Bulletin 1606-XL performance power supply family. This three-phase, conformal-coated version delivers a nominal 24V DC output at 480W rated power. Engineers select it for high-load cabinets where single-phase input is unavailable or impractical.

Three-phase input reduces current draw per line, which lowers conductor sizing requirements. Additionally, conformal coating protects the internal circuitry from harsh conditions. The unit carries UL 60950-1, cUL, and CE approvals for global deployment.

Technical Specifications

The 1606-XLS480E-3C accepts three-phase AC input for industrial power distribution. Specifically, input voltage spans 380...480V AC three-phase nominal, matching common European and Asian grid standards.

Output voltage is 24V DC nominal and adjusts from 24...28V. Output current reaches 20A nominal, derating to 17.5A across the range. Meanwhile, typical efficiency sits at 95.0%, which significantly reduces heat buildup inside enclosures.

Ripple and noise stay below 100mV maximum (mVpp). This clean output protects sensitive controllers and sensors. The DC OK relay contact provides status feedback to monitoring systems, and spring terminals simplify wiring during commissioning.

No communication ports exist on this unit. Therefore, it serves purely as a power conversion device without protocol support.

Mechanical and Environmental Parameters

Dimensions measure 65 × 124 × 127 mm (W×H×D). The compact housing fits standard DIN rail layouts, and the unit weighs approximately 870 g without packaging.

Operating temperature ranges from -25 to +70°C. Storage temperature spans -40 to +85°C for non-operating periods. Besides thermal tolerance, relative humidity reaches 5 to 95% non-condensing. The IP20 protection rating suits enclosed cabinet mounting only.

Installation Guide

First, verify the DIN rail is clean and securely fastened inside the cabinet. Next, snap the 1606-XLS480E-3C onto the rail until the latch clicks. Then connect three-phase input wiring to the spring terminals per the terminal diagram.

After wiring, set the output voltage using the front adjustment potentiometer. Specifically, turn the screw until a meter reads the target value between 24V and 28V. Finally, connect the DC OK relay to your monitoring circuit if needed.

Ensure adequate ventilation around the unit. Moreover, keep clearance above and below the housing for convection cooling. The conformal coating does not permit immersion or washdown cleaning. Verify phase sequence and voltage before energizing the unit.

FAQ

Q1: What distinguishes the 1606-XLS480E-3C from single-phase models?
A: This unit accepts 380...480V three-phase input. Therefore, it suits high-power cabinets where balanced loading across phases matters.

Q2: Why choose the conformal-coated version?
A: The coating protects the PCB from moisture, dust, and corrosive gases. Consequently, it extends service life in harsh process environments.

Q3: How does the 50% power reserve help my application?
A: The reserve supplies extra current briefly during motor startup. Specifically, nuisance trips decrease when inductive loads energize.

Q4: What is the purpose of the DC OK relay contact?
A: The relay signals output status to PLCs or alarm panels. Specifically, it closes when output voltage stays within tolerance.

Q5: Does this power supply include communication ports?
A: No. The 1606-XLS480E-3C has no communication interface. It operates as a standalone power conversion unit without protocol support.
