NOTE 1.    All parameters NOT specially mentioned are measured at rated input, rated load and 25℃ of ambient temperature. 2.    Measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1 uF & 47uF parallel capacitor. 3.The power supply is considered as a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
