All parameters need to measured under the conditions of rated voltage 220VAC input, rated load, ambient temperature of 20 degrees Celsius, and humidity of 70%.2. Accuracy: Including setting error, line adjustment rate, load adjustment rate, etc.3. Ripple Test: Connect the power supply and the load with a 30CM long stranded wire, connect 0.1u and 47u capacitors at the load end, and measure with a 20Hz oscilloscope at the load end.4. Line Regulation Rate: Under rated load conditions, the input voltage is measured from low to high change.5. Load Regulation Rate: The measured output is measured from 0% load to 100% load change.6. Each channel can output the maximum current, but the sum of the total load cannot exceed the maximum output power.
