1606-XLS960E-3 | Allen-Bradley | 24 V DC 960 W Three-Phase Power Supply
The Allen-Bradley 1606-XLS960E-3 is a Bulletin 1606-XL performance power supply. It delivers 24 V DC at 960 W from a 380–480 V AC three-phase input. Output is adjustable from 24 to 28 V DC at up to 40 A. The series adds BonusPower reserve rated at 60 A for transient peaks. A DC OK relay contact reports output health. Screw terminals suit field wiring in high-current cabinets. Typical efficiency is 95.3%, with 20 ms hold-up time. This unit targets panels with three-phase power and dense 24 V DC loads.

Bulletin 1606-XL — Engineering Notes
Three-phase input changes the design math. The 1606-XLS960E-3 draws balanced current from 380–480 V AC feeds. This suits plants with three-phase busbars near the cabinet. The 60 A BonusPower reserve gives short bursts for inrush-heavy loads. 95.3% efficiency cuts heat inside sealed enclosures. 20 ms hold-up bridges brief input dips. Screw terminals hold large conductors for 40 A output. The DC OK relay lets a PLC watch the rail without extra hardware. No bus port keeps the device simple and panel wiring clean.
Suitable Equipment and Applications
- Large control panels with three-phase 380–480 V AC supply.
- Machines driving many 24 V DC loads at up to 40 A continuous.
- Allen-Bradley and Rockwell Automation cabinet builds.
- Systems with high inrush devices such as contactor banks and drives.
- Retrofit projects replacing oversized or aging three-phase supplies.
Installation Notes
- Mount on DIN rail or wall. Respect IP20 enclosure requirements.
- Confirm three-phase input voltage and phase sequence before power-up.
- Use screw terminals rated for the output conductor size.
- Set output with a meter under load. Range: 24–28 V DC.
- Wire the DC OK relay to a PLC input for rail monitoring.
- Keep clearance for airflow. Derate near +70 °C.

Oiltech Controls Insight — Field Review
The 1606-XLS960E-3 fits panels that already run three-phase power. It avoids adding a step-down transformer for the 24 V rail. The 60 A reserve is the headline feature for engineers fighting nuisance trips during simultaneous startup. Screw terminals handle 40 A output conductors better than spring clamps in some high-current builds. The DC OK relay is a practical touch for HMI alarms. No communication port means no remote data, so plan a PLC input if you want status logging. Check derating at high ambient temperature before you size the load.
FAQ — Practical Selection Guidance
Q: Can I run the 1606-XLS960E-3 on a single-phase feed?
A: No. This model requires 380–480 V AC three-phase input. For single-phase sites, choose the 1606-XLS480E. Confirm your supply type before ordering.
Q: How much load can the 60 A BonusPower reserve support?
A: It covers short transient peaks only. Do not size continuous loads to 60 A. Base the continuous design on 40 A at 24 V DC, then use the reserve for inrush events.
Q: What does 20 ms hold-up time mean for my machine?
A: The output stays in regulation for about 20 ms after input loss. This bridges brief dips and prevents PLC resets. It does not replace a UPS for longer outages.
Q: Screw terminals or spring clamps — why does this model use screws?
A: High-current output needs firm, large-contact terminations. Screw terminals handle bigger conductors and stay tight in high-vibration cabinets. Re-torque during routine maintenance.
Q: Should I buy a tested surplus unit for a three-phase panel?
A: For urgent repairs, yes. Ask for a load test report before shipment. We verify output and relay function. The 12-month warranty covers defects. Email info@oiltechcontrols.com with your panel details.
