Product details
Product Overview
The 1606-XLS480E-3 is a three-phase switched-mode power supply from the Allen-Bradley Bulletin 1606-XL series. It delivers a regulated 24 V DC output with 480 W rated power. The wide 380…480 V AC three-phase input suits heavy machinery and plant-level distribution. BonusPower provides a typical 30 A at 24 V DC for 4 s. This helps trip breakers and start DC motors with high inrush. The DC OK relay contact gives a clear status signal. Spring clamp terminals speed up wiring. The unit mounts on DIN rail or directly on a wall. Marine approvals ABS, GL and RINA extend use to shipboard systems.

FAQ
Q: What happens during a high inrush startup?
A: BonusPower delivers about 30 A at 24 V DC for 4 s. This trips breakers and starts DC motors.
Q: Do I need a neutral wire?
A: No. The input is three-phase 380…480 V AC without a neutral.
Q: Can I run it on DC input?
A: Yes. Operational DC input spans 450…780 V.
Q: How do I confirm the output is healthy?
A: The DC OK relay contact reports status to your control system.
Q: Is the output adjustable on site?
A: Yes. The front adjuster sets 24…28 V DC.
Q: What causes derating?
A: Ambient above +60 °C reduces available output. Plan cabinet cooling.
Q: Why does my supply trip at startup?
A: Check phase loss and terminal torque first. Then confirm the load stays within 20 A continuous.
Q: Can I use it on a ship?
A: Yes. It carries ABS, GL and RINA marine approvals.
