    NOTE

     

    1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C 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. For guidance on how to perform these EMC tests, please refer to .EMI testing of component power supplies’’

    (as available on http://www.meanwell.com)

    5. Mounting holes M1 and M2 should be grounded for EMI purposes.

    6. Heat Sink HS1,HS2 can not be shorted.
