Troubleshooting
No DC output voltage
Verify AC input voltage is within the 85-264V range. Check all input and output wiring connections for security. Ensure the load does not exceed the 30W (2.5A) limit.
Unit overheating or shutting down
Ensure ventilation slots are clear and the ambient temperature is within the operating range (-25°C to 70°C). Verify the load is not exceeding the maximum power rating.
Intermittent power delivery
Check AC input connections for stability and potential voltage drops. Inspect output wiring for loose connections or short circuits.
Low output voltage
Confirm the AC input voltage is stable and within the specified range. Check if the connected load is drawing more current than the supply can provide.
Pros and Cons
