Note:

1.The testing condition for the parameter above is: 230VAC input, rated load, 25ºC 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 & 47UF capacitor short-circuit for interrupting.
4.Inlet voltage stability test:when is over load,the lowest voltage of inlet is up to the highest voltage.
5.Load stability test:the load is from 0% to 100%.
