Caution.

1. All parameters are measured at rated voltage 220V AC input, rated load, ambient temperature 25°C, humidity 70%.

2. Accuracy: including setting error, voltage adjustment rate, load adjustment rate

3. Ripple test: connect power supply and load with 30CM long stranded wire, connect 0.1uF ceramic capacitor and 10uF capacitor to the load, test with 20MHz oscilloscope at the load end

4. Voltage regulation: Under the rated load condition, the input voltage is measured from low to high.

5. Load regulation: measured from 1% load to 100% load of the output under test
