……

Note:1.The testing condition for the paramenter above is: 230 VAC input, rated load, 25  70% Rh, temperature.

2.Error.include the setting error.line stability and load stability.(Note:5)

3.Wave test:adopting “A12”double wire for 20MHzand 0.1UF&0.47UF capacitor short-circuit for interrupting

4.Intel 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%.
