FAQ

Q: Can this power supply be used redundantly?
A: For redundant power configurations, use multiple power supplies with OR-ing diodes or a dedicated redundant power supply module.

Q: What happens if the load exceeds 30W?
A: The power supply enters current-limiting mode. Persistent overload may trigger thermal shutdown with automatic recovery.

Q: Is this suitable for hazardous locations?
A: Verify specific hazardous location ratings. The power supply itself may require installation in a non-hazardous area with intrinsically safe barriers for field wiring.

Selection Tips

• Calculate total system power requirement including I/O modules, FTAs, and field devices
• Include 20-30% margin for future expansion
• For higher power requirements, consider FC-PSUNI-2424 or multiple power supplies
• Verify input voltage compatibility with site power infrastructure
