Compatibility & Applications

Designed for ABB S4C+ controller cabinets. Provides reliable DC power for main computer boards, I/O modules, safety systems, and external sensors in automotive, welding, material handling, and packaging applications.

FAQ

• Q: What power rating do I need? A: Calculate total 24V DC current draw of all modules in your S4C+ cabinet. Typical configurations use 300W or 1000W depending on I/O count and external device loading.
• Q: Is the input voltage auto-ranging? A: Yes, most DSQC 539 variants support 100-240V AC auto-ranging input, eliminating manual voltage selection.
• Q: Can DSQC 539 be used in IRC5 controllers? A: No, DSQC 539 is designed for S4C+ systems. IRC5 controllers use DSQC 609, DSQC 627, or DSQC 505 power supplies.
• Q: What protection features are included? A: Overvoltage, overcurrent, and short-circuit protection safeguard the power supply and connected modules.

Installation Guide

1. Power off the S4C+ controller and disconnect AC mains.
2. Wait 5 minutes for capacitor discharge.
3. Remove the existing DSQC 539 from its mounting position.
4. Install the new power supply module, ensuring proper ventilation clearance.
5. Connect AC input to the terminal block with correct wire gauge.
6. Connect 24V DC output to the controller distribution bus.
7. Verify earth ground connection.
8. Restore power and confirm output voltage is 24V DC ±5%.

Selection Tips

• Select DSQC 539 (3HAC14265-1) for S4C+ controller power supply replacement.
• Verify required power rating (300W vs. 1000W) based on your system's total current consumption.
• Check input voltage compatibility with your facility supply (100-240V AC range covers most regions).
• For IRC5 systems, order DSQC 609 (3HAC14178-1) or DSQC 627 (3HAC020466-1) instead.
