Remark *In order to extend the lifetime, it is recommended to configure the load more than 30% of the remaining allowance. For example: the power of the device requires 100W, then use the power of not less than 130W.
*Ripple test method: 20MHz oscilloscope in power output terminal test, oscilloscope probe wire length is not more than 12mm, and input parallel 47uF electrolytic capacitors and 0.1uF high frequency capacitance probe.
* The power supply is regarded as part of the internal components of the equipment, and it needs to be combined with the terminal equipment to complete the EMC related test and confirmation.
