Frequently Asked Questions

• Q: Can I use this supply outdoors?
• A: Only indoors (IP20). Protect from moisture and dust.
• Q: What happens if I overload the output?
• A: The supply limits current to ~3.2 A (constant current). It recovers automatically.
• Q: Is it compatible with 24 V AC loads?
• A: No. Output is DC only. Do not connect AC loads.
• Q (experiential): Why choose this over a cheaper supply?
• A: Longer MTBF, tight regulation, and global safety approvals reduce downtime and liability.
• Q (buying guide): How to decide between 2.5 A and higher current models?
• A: Calculate total load current. Add 20% margin. For 2.5 A, this unit is ideal for small PLC and sensor systems.
