Product details
Product Overview
The 1606-XLS480EC is a high-performance power supply from the Allen-Bradley Bulletin 1606-XL series. It delivers a stable 24 V DC output with 480 W rated power. This conformal-coated variant suits harsh industrial environments. A 50% power reserve supports peak loads and startup currents. The unit mounts on a DIN rail and uses spring terminals for fast wiring. An adjustable output and a DC OK relay contact simplify system monitoring.

FAQ
Q: Can this unit supply more than 20 A for short periods?
A: Yes. The 50% power reserve covers startup and peak loads.
Q: Does it need a separate communication module?
A: No. It has no communication ports. The DC OK relay handles status signals.
Q: How do I know the output is healthy?
A: Watch the DC OK relay contact. It signals output status to your control system.
Q: Is the output adjustable in the field?
A: Yes. You can set it from 24 V to 28 V with the front trim pot.
Q: Will the coating survive washdown?
A: The conformal coating adds protection. The unit still carries an IP20 rating, so avoid direct water jets.
Q: What should I check first if the supply trips?
A: Check input voltage and terminal torque. Then confirm the load stays within 20 A. Also verify airflow around the unit.
Q: Can I mount it in any orientation?
A: Mount it on DIN rail with clearance for cooling. Follow the installation guide for best results.
