NOTE

1.All parameter NOT specially mentioned are measured at rated input,rated load and 25°C of ambient temperature.2.Measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1µF & 10µF parallel capacitor.3.The SPS is considered a component which will be installed into final equipment.The equipment must be re-confirmed that it still meets EMC directives.
