I bought a meanwell 5V, 10A supply that I want to use in combination with this usb connector box. For each double socket I've put a 3A fuse in serie for extra shortcut protection.

Parts:
- meanwell MDR-60-5 power supply
- usb socket
- glas fuses
- rail mount for meanwell supply  a model I designed to mount the 5V supply onto my printer.
