NOTE 1.All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25¡æ of ambient temperature.
  2.Ripple & noise are measured at 20MHz of bandwidth by using a 12¡åtwisted pair-wire terminated with a 0.1¦Ì &47¦Ì
   parallel capacitor.
  3.Each output can within current range. But total output power can¡¯t exceed rated load.
  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.
