Selection Guide – Practical Tips

Choose this model if: You need a 5 A, 24 V supply with wide input and high reliability.
Consider parallel operation: Use two units for up to 10 A output (with proper external diodes).
Derating awareness: Above +45 °C, reduce current by 1.6% per °C to maintain performance.
Mounting: DIN rail mounting is easiest; ensure top/bottom spacing for cooling.
Use a buffer module: For critical loads, add a buffer to bridge short power failures.
