1606-XLE960MX-3N Allen-Bradley Power Supply – 3-Phase 48 V DC, 960 W, Bulletin 1606-XL
The 1606-XLE960MX-3N is an Essential-class switched-mode supply in the Allen-Bradley Bulletin 1606-XL line. It runs on 3-phase AC 400/480 V and delivers a semi-regulated 48 V DC output at 960 W and 20 A. Efficiency hits 96.0% typical, with losses near 40 W. The design uses screw terminals and a DIN rail body. Ripple runs up to 2500 mVpp because the output is semi-regulated. Power factor is 0.93 typical. This unit is End of Life. Rockwell discontinues it December 31, 2026. The engineering replacement is 1606-XLS960F. Buyers still running 3-phase 48 V panels should plan a migration path now.

What This Supply Suits
- 3-phase cabinets feeding 48 V DC motor brakes and contactors
- Heavy 48 V loads where tight regulation is not critical
- Legacy panels built around the 1606-XLE footprint
- High-power DC bus segments near 1 kW
- Retrofit jobs that must match existing screw-terminal wiring
Wiring and Start-Up
- Mount on DIN rail. Keep airflow paths open.
- Feed all three phases at 400 V or 480 V AC.
- Use screw terminals. Torque to spec.
- Accept the semi-regulated 48 V. Expect ripple up to 2500 mVpp.
- Apply derating above +60 °C: 24 W/°C.
- Check phase rotation and balance at commissioning.
Oiltech Controls Review
This is a workhorse unit, not a precision rail. The 96% efficiency keeps heat down at 960 W. The semi-regulated output is fine for contactors and brakes. It is not fine for sensitive 48 V electronics. Ripple at 2500 mVpp is high by design. The EOL date matters most. If your panel depends on this footprint, buy tested spares now.
Oiltech Controls Insight
- Reserve stock before December 31, 2026.
- Ask for ripple and load-bank test data on used units.
- Match the replacement 1606-XLS960F to your load type first.
- Do not pair with sensitive 48 V logic without filtering.

FAQ
Can I replace 1606-XLE960MX-3N with 1606-XLS960F directly?
Check wiring, footprint and load type first. The replacement is regulated and may need different fusing. Ask us for a comparison sheet before you swap.
Why is ripple so high at 2500 mVpp?
The output is semi-regulated by design. Use filtering if your load is sensitive. Contactors, brakes and lamps tolerate it well.
Should I stock spares before the EOL date?
Yes. Rockwell discontinues the unit on December 31, 2026. Tested spares protect uptime after that cutoff.
What should I verify on a used unit?
Ask for load-bank data, ripple measurement and screw-terminal condition. Oiltech Controls tests each unit before shipment.
Is this unit right for a new panel design?
No. Choose the current regulated 1606-XLS960F for new builds. Keep the 1606-XLE960MX-3N for legacy maintenance only.
