Warm tips:
1. All parameters in the rated voltage 220VAC input, rated load environment 25 ℃, humidity 70% of the conditions of measurement
2. Precision: including setting error, voltage adjustment rate, load adjustment rate
3. Ripple test: connect the power supply and load with 30cm long stranded wire, and 0.1uF and 47uF capacitors at the load side, measured by 20MH oscilloscope at the load side.
4. Voltage regulation rate: under rated load conditions, the input voltage is measured from low to high.
5. Load adjustment ratio: measured from 0% load to 100% load variation of the output under test.
6. Each channel can output the maximum current, but the sum of the total load can not exceed the maximum output power
