    NOTE

    1.     All parameters 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 0.1 uF & 47uF 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.
