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&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%.
