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 0.1μ & 47μ 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.
