1. All parameters NOT specially mentioned are measured at230VAC input, rated load and 25 _ of ambient temperature.
2. Ripple & noise are measured at20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation and load regulation.
4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets
EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”
5. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
6. The ambient temperature derating of 3.5
/1000m with fanless models and of
5
/1000m with fan models for operating altitude higherthan 2000m(6500ft).
