1.All parameters are specified at normal input, rated load, 25℃ 70% RH ambient.

2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.

3.Line regulation is measured from low line to high line at rated load.

4.Load regulation is measured from 0% to 100% rated load.

NOTE

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)
