Note: 1. The testing condition for the paramenter above is: 230VAC input, rated load, 25°c 70% RH. Temperatuer. 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 woltage 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%
