1606-XL480E-3 Allen-Bradley 480W 3-Phase PSU | Oiltech

1606-XL480E-3 | Allen-Bradley | 24 V DC 480 W Three-Phase Power Supply (Discontinued)

The Allen-Bradley 1606-XL480E-3 is a legacy Bulletin 1606-XL switched-mode power supply. It delivers 24 V DC at 20 A (480 W) from a 400–480 V AC three-phase input. A 600 W boost gives 25 A for short periods at 0–45 °C. Output is preset to 24 V ±0.5% and adjustable to 28 V DC. DIN rail mounting follows 1606-AP023. Rockwell ended sales on 2017-10-30. The listed direct replacement is the 1606-XLS480E-3. We source tested units for plants that still run this platform.

Bulletin 1606-XL Legacy — Engineering Notes

The 1606-XL480E-3 belongs to an earlier generation of the 1606-XL family. It runs from three-phase mains without a step-down transformer. The 600 W boost supports inrush loads such as contactor coils and small drives. Ripple stays below 20 mVpp, which suits sensitive 24 V logic. Hold-up above 11 ms bridges short input dips. This unit is discontinued, so replacement planning matters. The official successor is the 1606-XLS480E-3. Check wiring and mounting differences before you swap. Keep a tested spare for legacy lines that cannot be re-engineered.

Where It Fits — Compatible Equipment

• Legacy panels built around Bulletin 1606-XL supplies.
• Three-phase 400–480 V AC cabinets with 24 V DC control loads.
• Machines requiring 480 W continuous or 600 W short-term boost.
• Retrofit and repair projects for discontinued Rockwell hardware.
• Systems with ripple-sensitive logic below 20 mVpp.

Installation Notes

• Mount on DIN rail per 1606-AP023. Allow convection clearance.
• Verify three-phase input voltage and phase sequence first.
• Set output with a meter under load. Range: 24–28 V DC.
• Apply derating above +60 °C ambient.
• Keep the open-frame unit inside an IP20-compliant enclosure.
• Plan for the 1606-XLS480E-3 if a permanent replacement is needed.

Oiltech Controls Review — Field Insight

The 1606-XL480E-3 still appears in older three-phase panels that run fine and cannot be rebuilt. Its 600 W boost covers startup peaks without tripping. The 92% efficiency and low ripple suit mixed logic and relay loads. The catch is lifecycle: it is discontinued. Buy a tested spare, confirm output under load, and plan a path to the 1606-XLS480E-3. Engineers value the DIN rail format and straightforward screw-free termination. Check the enclosure airflow before you push toward 60 °C ambient.

FAQ — Practical Guidance

Q: Is the 1606-XL480E-3 still available new from Rockwell?

A: No. Rockwell ended sales on 2017-10-30. We supply tested surplus and refurbished units. Confirm condition and warranty before you order.

Q: Can I replace the 1606-XL480E-3 with the 1606-XLS480E-3 directly?

A: Rockwell lists it as the direct replacement. Check input wiring, mounting, and terminal layout first. Compare both datasheets before you swap in a running panel.

Q: What does the 600 W boost actually cover?

A: Short current peaks up to 25 A at 0–45 °C. Do not size continuous loads to 600 W. Use it for inrush from contactors or small drives.

Q: Why is ripple and noise below 20 mVpp important?

A: Low ripple protects sensitive analog and logic circuits on the 24 V rail. It also reduces false trips on threshold-based inputs. Measure ripple under load if your process is noise-sensitive.

Q: How should I plan spares for a discontinued supply?

A: Buy a tested unit and keep it on the shelf. Record the load current and ambient temperature. Contact info@oiltechcontrols.com for stock and test reports. The 12-month warranty covers functional defects.
