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 SPS is considered a component which will be installed into final equipment. The equipment must be re-confirmed that it still meets EMC directives.
