Note
1.The testing condition for the paramenter above is :230VAC input,rated load,2570% 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&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%.
6.Total output canbe maximum Current,total load can not exceed the maximum output power
7C₂₃₁₁ must be knocked down.
