Remarks:

Unless otherwise specified, all specifications are measured under the input of 220VAC, rated load, and 25°C ambient temperature.

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.

Accuracy: including setting error, linear adjustment rate and load adjustment rate.

Linear adjustment rate measurement method: under rated load, from low voltage to high voltage test.

Load regulation measurement method: From 0% to 100% rated load.

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.
