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.Tolerance: includes set up tolerance, line regulation and load regulation.
4.Within 30 minites, the peak value proportion is 33.3%, average rated power can not exceed rated power.
5.The power supply is considered as a component inside the equipment, the final equipment must be confirmed it meets EMC directives.
