Allen-Bradley 1606-XLS480G-3 36V 480W PSU

Allen-Bradley 1606-XLS480G-3 36V DC Power Supply

Product Introduction

The 1606-XLS480G-3 is a performance switched-mode power supply from the Allen-Bradley Bulletin 1606-XL series. This unit runs on 3-phase AC 380–480 V input and produces a regulated 36 V DC output. It delivers 480 W of rated power with 13.3 A nominal current. Engineers use this model for heavy machinery, conveyor systems, and large control panels fed from 3-phase mains.

The 1606-XLS480G-3 carries UL 60950-1, cUL, and CE approvals. Its 94.8% typical efficiency keeps cabinet heat low. Moreover, a 150% power boost handles motor starting and capacitor charging without shutdown. Spring clamp terminals speed up wiring, and a DC OK relay contact reports output status for diagnostics.

Technical Specifications

The 1606-XLS480G-3 accepts 3-phase AC 380–480 V input. Output voltage is DC 36 V nominal, adjustable from 36 V to 42 V. Output current reaches 13.3 A nominal, with a range of 13.3 A to 11.4 A across the adjustment band. Rated power is 480 W.

Efficiency reaches 94.8% typical, and typical power losses are only 26.3 W. Ripple and noise stay at 100 mVpp maximum. Power factor is 0.94 typical, which meets modern mains quality expectations. An active input inrush current limiter protects upstream breakers. Derating runs at 12 W/°C from +60 to +70 °C. Additionally, the 150% power boost covers short overload peaks.

Mechanical and Environmental Parameters

The unit body measures 124 mm high × 65 mm wide × 127 mm deep. It weighs 0.87 kg, keeping DIN rail loading manageable. 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 is not published in Bulletin 1606-TD002.

The slim 65 mm width saves rail space in dense cabinets. Furthermore, screw and spring clamp terminals accept a range of wire sizes.

Installation Guide

First, snap the 1606-XLS480G-3 onto a standard 35 mm DIN rail inside the control cabinet. Next, connect the three phase conductors to the L1, L2, and L3 terminals. Then wire the 36 V DC output to the load circuit, observing polarity marks.

After wiring, set the output voltage with the front potentiometer between 36 V and 42 V. Finally, connect the DC OK relay contact to a monitoring input for status feedback. Mount the unit vertically and keep clearance above and below for convection cooling. Check the derating curve above +60 °C before full-load operation.

FAQ

Q1: What input voltage does the 1606-XLS480G-3 require?
A: The unit accepts 3-phase AC 380–480 V. It suits panels fed from standard industrial 3-phase mains.

Q2: What is the output rating of this power supply?
A: It provides 36 V DC at 13.3 A nominal, or 480 W rated power. Output adjusts from 36 V to 42 V.

Q3: What does the 150% power boost provide?
A: The supply can deliver brief peaks up to 150% of rated power. This boost supports motor starting and capacitor charging without shutdown.

Q4: Does the 1606-XLS480G-3 include communication?
A: No. It has no communication port or protocol. It does provide a DC OK status indicator and relay contact for basic monitoring.

Q5: How does temperature affect output power?
A: Full power is available up to +60 °C. Above that, derating applies at 12 W/°C up to +70 °C. Plan cabinet cooling accordingly.
