1. All parameters NOT specially mentioned are measured at normal input (5V/12V/24V/48V) , rated load and 25 of ambient temperature. ℃

2. Derating may be needed over high . Please check the derating curve for more details. temperatureambient

3. The ambient temperature derating of 3.5 /1000m with fanless models and of 5 /1000m with fan models for operating altitude ℃℃

higher than 2000m(6500ft).

4. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with

the EMC directives. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.
