Note:
1. The above parameter testing conditions are: 230VAC input, rated load, 25 ℃ 70% RH. Humidity.
2. Tolerance: including set tolerance, line stability, and load stability (Note 5).
3. Ripple test: Use A12 "twisted pair for 20MHz and short-circuit with 0.1uF&47uF capacitors for interruption.
4. Incoming voltage stability test: the lowest voltage to the highest voltage of the incoming line at full load.
5. Load stability test: load from 0% to 100%.
