description / manual

USB has three USB Type A sockets and an on/off switch.


You don´t need a +5V power rail on your PSU. „USB“ internally converts +12V to +5V.


The third socket is also registered for charging mobile devices. It supplies +2V on the D− and D+ lines of the USB socket showing the device that it may charge a maximum of 500mA (this is an Apple standard, though charging of other brands worked well, too).


As USB directly draws current from your PSU, make sure you have enough „current headroom“ available. Don´t use this module to power devices that draw more than an absolute maximum of 800mA in total, it is recommended to keep it below 500mA.
