Product Overview
1606-XLS480G-3 is a 3-phase switched-mode power supply from the Allen-Bradley Bulletin 1606-XL series. It delivers a 36 V DC output at 480 W. The unit mounts on a DIN rail and uses spring clamp terminals. Moreover, a DC OK LED and a DC OK relay contact show output status. A 150% power boost gives extra reserve for high-load starts.
This PSU has no communication port and no protocol support. In other words, it is a pure power module. It suits cabinets that need a stable 36 V rail. Because it runs from a 380…480 V AC 3-phase line, it fits most plant mains. Efficiency reaches 94.8% typical. Also, the active inrush limiter reduces start-up stress on breakers.

Installation Guide
- Clip the unit to a DIN rail in the cabinet.
- Keep clear space above and below for airflow.
- Wire the 3-phase AC line to the input terminals.
- Tighten the spring clamp or screw terminals fully.
- Set output with the trim pot. Range is 36…42 V DC.
- Check the DC OK LED after power-up.
- Use the DC OK relay for a remote status signal.
- Plan derating above +60 °C. Loss is 12 W/°C.
Setup and Maintenance
Setup is simple because there is no software and no configuration port. You only set the output voltage by trim pot. In addition, the DC OK contact helps with fast fault finding. Maintenance is low. Clean the vents. Check terminal torque. Verify output voltage at each service visit. Meanwhile, the active inrush limiter lowers wear on upstream breakers.
Compatibility Notes
The 1606-XLS480G-3 fits standard DIN rail systems. It works with 3-phase 380…480 V AC mains. Also, the 36 V DC rail suits 36 V loads and 36…42 V adjustable loads. It has no bus or network link. Therefore, pair it with hard-wired relays and contactors. Check load current against the 13.3 A nominal rating. Use the 150% boost only for short peaks.
Approvals and Certifications
- UL 60950-1
- cUL
- CE marked, per the official Bulletin 1606 series standard
Diagnostics
Two tools give fast status. The DC OK LED shows output health at a glance. Also, the DC OK relay contact sends a dry signal to a PLC or alarm. There is no digital diagnostics port. Instead, fault tracing relies on the LED, the relay, and a meter check of the 36 V rail.
Typical Applications
- 36 V DC control panels in factories
- 3-phase machine cabinets
- Replacement PSU for old Bulletin 1606 systems
- Loads that need short 150% current peaks
- Plants with 380…480 V AC 3-phase supply
