I am trying to power my raspberry pi model 3 model b+ using this DC power supply. According to the official FAQ the power requirements seems suitable. But, I am not how to use the power supply to power the raspberry pi. How do I connect the terminals and use some sort of usb converter to connect the raspberry pi? What should be the settings on the power supply? The reason I went for the power supply was because after trying about a dozen usb power adapters (androind chargers), it didn't work and every time the pi powers up, the under voltage sign is displayed.
Hope I explained this properly. Not an electrical engineer so, some guidelines will be highly appreciated.
