2. Derating may be needed over high

. Please check the derating curve for more details.

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.”
