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.
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%.
Every year we john 2-3 fairs to meet our customers. What we show is our ability, and what you feel will be our profession.
