Remarks	1. Unless otherwise specified, all specifications are measured under the input of 220VAC, rated load, and 25°C ambient temperature.
	2. Ripple and noise measurement method: use a 30CM twisted pair cable, and the terminals should be connected in parallel with 0.1uf and 47uf capacitors, and measure at 20MHZ bandwidth.
	3. Accuracy: including setting error, linear adjustment rate and load adjustment rate.
	4. Linear adjustment rate measurement method: under rated load, from low voltage to high voltage test.
	5. Load regulation measurement method: from 0% to 100% rated load.
	6. The power supply should be regarded as a part of the components in the system, and the relevant confirmation of electromagnetic compatibility should be carried out in conjunction with the terminal equipment.
