Note * In order to prolong the service life, suggest to leave 30% of the allowance when loading. For example: equipment requires for 100W, we should choose not less than 130W power supply.
* The ripple test method of switch power supply: Test with 20 MHZ oscilloscope on the output terminal, the ground wire length of oscilloscope is not more than 12 mm, parallel 47 uF electrolytic capacitor and 0.1 uF high-frequency capacitance at the input of oscilloprobe.
* All the electrical performance testing are completed in 25 ℃ environment.
