Allen-Bradley 1606-XLS480F 48V 480W Power Supply

Allen-Bradley 1606-XLS480F 48V DC Power Supply

Product Introduction

The 1606-XLS480F is a performance-class power supply from the Allen-Bradley Bulletin 1606-XL series. This unit converts AC 100–240 V or DC 110–150 V input into a regulated 48 V DC output. It delivers 480 W of rated power with 10 A nominal output current. Engineers select this model for motor drives, solenoid banks, and high-power sensor networks that require 48 V DC rails.

The 1606-XLS480F carries UL 60950-1, cUL, and CE approvals. Its 94.3% typical efficiency keeps heat low inside sealed cabinets. Meanwhile, the 50% power reserve supports short load peaks without shutdown. A DC OK relay contact reports output status to the control system for diagnostics.

Technical Specifications

The 1606-XLS480F accepts AC 100–240 V nominal and DC 110–150 V input. Output voltage is DC 48 V nominal, adjustable from 48 V to 55 V. Output current reaches 10 A nominal, with a range of 10 A to 8.7 A across the adjustment band. Rated power is 480 W.

Efficiency reaches 94.3% typical, which reduces energy loss and cabinet temperature. Ripple and noise stay at 100 mV maximum (mVpp). Additionally, the 50% power reserve allows brief overloads for motor starting or capacitor charging. The DC OK relay contact provides a dry signal for PLC monitoring. No communication interface or protocol is present, since the unit performs pure power conversion.

Mechanical and Environmental Parameters

The housing measures 124 mm high × 82 mm wide × 127 mm deep. It weighs 1200 g, so verify DIN rail load capacity during layout. Protection rating is IP20, suitable for enclosure mounting. Operating temperature spans -25 to +70 °C. Storage temperature ranges from -40 to +85 °C non-operating. Relative humidity covers 5 to 95% non-condensing.

Spring terminals accept solid and stranded wires without screw tightening. Furthermore, the compact width of 82 mm saves rail space in dense cabinets.

Installation Guide

First, snap the 1606-XLS480F onto a standard 35 mm DIN rail inside the control cabinet. Next, connect the AC input to the L and N terminals, or wire the DC input to the positive and negative terminals. Then connect the 48 V output to the load circuit, observing polarity marks.

After wiring, set the output voltage with the front potentiometer between 48 V and 55 V. Finally, wire the DC OK relay contact to a monitoring input if status feedback is needed. Mount the unit vertically and keep clearance above and below for convection cooling. Do not block the ventilation slots on the housing.

FAQ

Q1: What is the output rating of the 1606-XLS480F?
A: The unit provides 48 V DC at 10 A nominal, or 480 W rated power. Output adjusts from 48 V to 55 V.

Q2: What does the 50% power reserve mean?
A: The supply can deliver brief peaks up to 150% of rated power. This reserve supports motor starting and capacitor charging without shutdown.

Q3: How efficient is this power supply?
A: Typical efficiency is 94.3%. This high value reduces heat generation and lowers cabinet cooling demand.

Q4: Does the 1606-XLS480F include communication?
A: No. It has no communication port or protocol. It does provide a DC OK relay contact for basic status monitoring.

Q5: What input voltages does the unit accept?
A: It accepts AC 100–240 V nominal and DC 110–150 V. This dual input range covers most industrial supply systems.
