Test conditions and notes5

1.All parameters NOT specially mentioned are measured at 230Vac input, rated load and 25℃ of ambient temperature.
2.Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3.Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
4.When starting at a low temperature of -40℃, the output capacitor needs to be equipped with a solid capacitor to meet the load reduction curve requirements.
5.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)
