Important Notes

All specifications are measured at 25°C ambient temperature, 230VAC input, and rated output load, unless otherwise stated.
Derating is required for high-altitude applications: above 2000m, the operating temperature must be derated.
A minimum load of 20% is required for stable startup and operation. Operating below this minimum may affect performance.
The built-in fan's airflow direction is from the vent holes on the large side surface to the opposite side (fan side). Ensure at least 50mm of clearance for air intake and exhaust.
The power supply is designed for end equipment installation. Final system EMC, safety, and thermal performance must be validated in the end application. Refer to the "Metal Enclosure Switching Power Supply Application Guide".
