Allen-Bradley 1606-XLS480EC Power Supply 480W

Allen-Bradley 1606-XLS480EC Performance Power Supply

Product Introduction

The 1606-XLS480EC belongs to the Allen-Bradley Bulletin 1606-XL performance series. It combines high output power with a conformal-coated circuit board. This coating protects internal electronics from moisture, dust, and corrosive elements. As a result, the unit suits demanding environments such as food processing, marine, and outdoor cabinets.

This model delivers a regulated 24V DC output at 20A. Specifically, it provides 480W of rated power with a typical efficiency of 93.9%. The 50% power reserve supports short-term peak loads without shutdown. Furthermore, spring terminals speed up wiring and resist vibration. Engineers frequently select this supply for panel builders who need durability and fast installation.

Technical Specifications

Electrical Parameters

The 1606-XLS480EC accepts AC 100...240 V nominal input. It also supports DC 110...150 V input for battery-backed systems. The output voltage is nominally DC 24 V, adjustable from 24 to 28 V. Additionally, the unit supplies 20 A nominal current, with a range of 20 to 17.7 A across the adjustment band.

Efficiency reaches 93.9% typical at full load. Ripple and noise stay at 100 mV maximum. Moreover, the 50% power reserve enables reliable startup of inductive loads such as motors and valves. The DC OK relay contact provides a dry signal for output status monitoring. Therefore, control systems can detect voltage faults immediately.

Mechanical and Environmental Data

The housing measures 124 mm in height, 82 mm in width, and 127 mm in depth. It weighs approximately 1200 g. The 1606-XLS480EC 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 conformal coating adds an extra barrier against condensation and airborne contaminants.

Installation Guide

First, snap the 1606-XLS480EC 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 wide-range input accepts both AC and DC sources without jumper changes.

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 within milliseconds.

FAQ

Q1: What does the conformal coating on the 1606-XLS480EC protect against?
A1: The coating shields the circuit board from moisture, dust, and corrosive gases. It also reduces the risk of condensation-related failures. Therefore, the unit performs well in humid or contaminated environments.

Q2: How much power reserve does this supply offer?
A2: The 1606-XLS480EC 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 without tripping.

Q3: What input voltages does the 1606-XLS480EC accept?
A3: The unit accepts AC 100...240 V nominal and DC 110...150 V. No manual selection is required. This flexibility supports both standard mains and battery-backed DC systems.

Q4: What type of terminals does this power supply use?
A4: 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 connection reliability improves.

Q5: What are the dimensions and weight of the 1606-XLS480EC?
A5: The unit measures 124 mm (H) x 82 mm (W) x 127 mm (D). It weighs approximately 1200 g. The 82 mm width fits standard DIN rail layouts in industrial control cabinets.
