Note:

1. The parameter under the testing condition: 230VAC input, rated load, 25℃ 70% 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%.
