1606-XL960E-3S Allen-Bradley 1606-XL 3-Phase Power Supply, 960 W
The 1606-XL960E-3S is a legacy Allen-Bradley Bulletin 1606-XL standard switched-mode power supply. It runs on 3-phase AC 400…500 V input and delivers 24…28 V DC at up to 40 A. Continuous rating is 960 W, with a 1080 W boost below one minute. The covered front potentiometer sets the output. Engineers pick this unit for heavy 24 V DC loads in legacy panels. The 1606-XL960E-3S is officially discontinued since October 30, 2017. Allen-Bradley lists the 1606-XLE960DX-3N as the direct replacement.
Oiltech Controls Review
A field note from our bench team on this legacy 3-phase unit.
- Input range is wide: continuous 340…575 V AC, short-term 300…620 V AC.
- Boost mode reaches 45 A at 24 V in the 0…45 °C window.
- Efficiency holds around 92.5% at 400 V AC and full load.
- Derating above +60 °C is about 24 W per Kelvin.
- Storage range of -25…+85 °C suits long warehouse storage.
- Screw terminals and DIN rail mount keep swap-outs fast.
- No communication port means fewer failure points in old panels.
- Most units we see still hold output well inside the trim range.
Oiltech Controls’s Insight: Where It Fits
- Legacy 3-phase machine panels already built around 1606-XL rails.
- Large 24 V DC buses feeding valve banks and contactor coils.
- Packaging and converting lines with 960 W continuous demand.
- Material handling systems with short 45 A peak loads.
- Retrofit projects where the direct replacement needs panel changes.
- Spare stock for discontinued Allen-Bradley power sections.

FAQ
Q: Is the 1606-XL960E-3S still available new from Allen-Bradley?
A: No. Official lifecycle status is discontinued since October 30, 2017. We supply tested surplus and refurbished units. The listed direct replacement is 1606-XLE960DX-3N.
Q: Can I run this unit on single-phase power during a bench test?
A: No. This is a true 3-phase input design. Single-phase feeding will not start the unit reliably and may damage it. Use a proper 3-phase supply for any test.
Q: How much headroom does the 1080 W boost give me?
A: The 45 A boost at 24 V holds only below one minute and only up to +45 °C. Size continuous loads at 40 A or lower. Use the boost for motor starts and capacitor inrush, not steady demand.
Q: Which unit should I choose, the original or the direct replacement?
A: Keep the 1606-XL960E-3S when the panel wiring and rail layout must stay unchanged. Choose the 1606-XLE960DX-3N for new builds. Check mounting, terminal layout and derating before you swap.
Q: How do I check a used unit before installing it?
A: Apply 3-phase input on a bench. Measure output across the trim range with a light load. Confirm it reaches 24 V and 28 V cleanly. Listen for fan or transformer noise. Reject any unit that sags under a step load.
