This just the PCB for a small USB powered busboard contains a meanwell power brick capable of supplying up to 410 mA on the +/-12V rail. It is powered using a 5V usb charger capable of delivering 2.5A. The 5V is also available on the bus board direct from the usb charger.
Like with any power supply you should not run it near it limit but 80% is enough for a mini case or for benchtop testing.

Lovingly built at Beepboop Electronics Workshop using quality parts.
