Important Notes

1. All specifications are measured at 25°C ambient temperature, 230VAC input, and rated output load, unless otherwise stated.
2. Derating is required for high-altitude applications: above 2000m, the operating temperature must be derated.
3. A minimum load (e.g., 10% for 5V model) is required for stable startup and operation.
4. Forced air cooling is recommended for full-load operation, especially at high ambient temperatures. Refer to the derating curves.
5. The ripple and noise measurement method uses a parallel 10µF ceramic capacitor and a 47µF electrolytic capacitor at the output.
6. The power supply is a component. Final system EMC, safety, and thermal performance must be validated in the end equipment.
7. Customized versions (e.g., modified output voltage) are available. Please contact us for specific requirements.
8. The "P" pin (case ground) must be connected to the system's protective earth (PE).
