Kind attention:

In order to extend the service life, it is recommended to leave an extra 30% margin when configuring the load. For example: if the device requires 100W of power, using a power supply of no less than 130W.

Switching power supply ripple test method: Use a 20MHz oscilloscope to test on the power output terminal. The length of the ground wire of the oscilloscope probe is no more than 12mm, and 47uF electrolytic capacitor and 0.1uF high-frequency capacitor are connected in parallel with the probe input.

All electrical performance tests are completed at 25C.

When the product is fully loaded, an aluminum plate with an area of ​​not less than 400*400*3mm must be added to assist the heat dissipation.

The power supply is a part of the equipment system components. All EMC tests are performed by installing samples on a metal plate. The power supply must be combined with the terminal equipment for electromagnetic compatibility-related confirmation.
