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