NOTE
1.All parameters are specified at normal input(A:12Vdc, B:24Vdc, C:48Vdc), rated load, 25 70% RH ambient. ℃
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1 f & 47 f capacitor. μμ
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 20% to 100% rated load.
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)
