4.Please Note1. 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. 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 inler is representative to the highest voltage. 5. Load stability test: the load is from 0% to 100%, others 60%. 6. C3.4 must be knocked down,
