NOTE	All parameters NOT specially mentioned are measured at 230VAC input,rated loadand 25℃ of ambient temperature.
	Ripple & noise are measured at 20MHz of bandwidth by using a 12”twisted pair-wire terminated with a 0.1uf &47uf parallel capacitor.
	Tolerance: includes set up tolerance.Line regulation and load regulation.
	Length of set up time is measured at first cold start .Turning ON/OFF the powersupply may lead to increase of the set up time.
