Product Introduction
The 1606-XLS960F-3 is a high-performance switched-mode power supply from the Allen-Bradley Bulletin 1606-XL family. Specifically, it belongs to the 1606-XLS series, which targets demanding industrial loads that need substantial 48 V DC power. It draws from a three-phase 380–480 V AC supply, a standard arrangement in larger machine and process panels. Engineers specify this model for motor drives, solenoid banks, and high-current control circuits. Its 50% power reserve supports short-term peak loads without voltage sag.
Technical Specifications
The 1606-XLS960F-3 delivers a nominal 48 V DC output with a rated current of 20 A. Additionally, the output is adjustable from 48 to 54 V for fine voltage trimming. Rated power reaches 960 W, and typical efficiency is an impressive 95.4%. Ripple and noise remain below 150 mVpp, which keeps downstream electronics stable. Moreover, the unit offers a 50% power reserve for transient peaks. The DC OK relay contact provides a clean status signal to control systems. As voltage rises across the adjustment range, current derates from 20 A to 17.8 A.
Mechanical and Environmental Parameters
The robust housing measures 124 × 110 × 127 mm and weighs 1500 g. Moreover, screw terminals provide reliable, high-torque connections for large conductors. The operating temperature range extends from -25 to +70 °C, which suits harsh plant environments. Storage tolerance spans -40 to +85 °C, and humidity tolerance covers 5 to 95% non-condensing. For safety, the unit carries UL 60950-1, cUL, and CE approvals. The 1606-XLS960F-3 also offers an IP20 protection rating for DIN rail or enclosure mounting.
Installation Guide
First, confirm the three-phase 380–480 V AC supply is available and correctly phased. Next, mount the unit vertically on a 35 mm DIN rail to support convection cooling. Then, connect the three input phases and the protective earth to the screw terminals. After that, wire the 48 V DC output to the load with correctly sized conductors. Finally, verify the DC OK relay wiring and adjust the output setpoint if needed. Always lock out the supply before commencing work.

FAQ
Q1: What input configuration does the 1606-XLS960F-3 require?
A: It requires a 380–480 V AC three-phase nominal input, which is typical for high-power industrial panels.
Q2: How does the 50% power reserve benefit my application?
A: The reserve supplies brief peak currents, so downstream drives and solenoids start without pulling the 48 V rail down.
Q3: What does the DC OK relay contact do?
A: The relay provides a dry contact signal that reports output status to a PLC or monitoring circuit.
Q4: Is the 1606-XLS960F-3 output voltage adjustable?
A: Yes. The output adjusts from 48 to 54 V, and rated current derates from 20 A to 17.8 A as voltage increases.
Q5: What terminals and mounting does this model use?
A: It uses screw terminals and mounts on a standard DIN rail. The IP20 rating applies to enclosure installations.
