    7. Please Note

    1. All parameters not specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 
    2. Ripple & noise are measured at 20MHz of bandwidth by using a 12 twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.  
    3. Tolerance : includes set up tolerance, line regulation and load regulation.
    4. Line regulation is measured from low line to high line at rated load.
    5. Load regulation is measured from 0% to 100% rated load.
    6. The power supply is considered a component which will be installed into a final equipment. The final equipment must be rre-confirmed that it still meets EMC directives. For guidance on how to perform these EMS test, please refer to "EMI testing of component power suppliers."
