Note: 1.*The “Tip and barrel method” is used for ripple and noise test, output parallel 47uF electrolytic capacitor and 0.1uF ceramic capacitor, please refer to
Enclosed Switching Power Supply Application Notes for specific information.
2.*Minimum load: When the product is working at a temperature above 50 , the minimum load is 5% of the rated load, so that the fan could work at℃
high temperature to reduce the temperature rise of the product.
3.*Over-current Protection: Test at rated output voltage, lo is rated output current load.
4.*Over-temperature Protection needs to be tested under rated full load conditions.
