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. (Note:5)
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 inlet is representative to the highest voltage.
5. Load stability test: The load is from 0% to 100%, others 60%.
6. C2、3、11must be knocked down.
