FAQ

Q1: How to choose the right power supply for my device?

First confirm your device’s required voltage and current. Select a power supply with the same voltage and rated current greater than or equal to your device’s needs for stable and safe operation.

Q2: How to troubleshoot interrupted or unstable DC output from a switching power supply?

If the fuse is intact but no DC output occurs under load, check for open/short circuits, protection triggers, or component failures in the high-frequency rectification/smoothing circuit. Use a multimeter to test secondary components: total output loss points to a control circuit issue, while partial output or instability points to failed rectifier diodes or leaking filter capacitors.
