Note:
1. The parameter under the testing condition: 230VAC input, rated load, 25°C70% RH. Temperature.
2. Tolerance: Including setting tolerance, circuit stability and load stability. (Note: 5).
3. Wave test: Adopting “A12” double wire for 20MHz, and 0.1 UF&47UF capacitor short-circuit for interrupting.
4. Inlet voltage stability test: the lowest voltage will be up to the highest voltage when the circuit overload.
5. Load stability test: The load is from 0% to 100%.
6.C3, 4 must be knocked down.
