    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.
    5. Harmonic current test @ 90% load.
    6. Under short circuit or overload >150% conditions, output voltage may shut down for 5 sec. and then go into constant current

    7.Please Note

    1. The testing condition for the parameter above is: 230VAC input, rated load, 25℃ 70%Rh, Humidity.
    2. Error, include the setting error, line stability and load stability.
    3. Wave test: adopting "A12" double wire for 20MHZ, and 0.1uF&uF capacitor short-circuit for interrupting.
    4. Inlet Voltage Stability test: when is over load, the lowest voltage of inler is representative to the highest voltage.
    5. Load stability test: the load is from 0% to 100%, others 60%.
    6. Total output canbe maximum Current, total load can not exceed the maximum output power.
    7. C3,4,11 must be knocked down.
