Description:  For sensors and circuits that need to run on 5 to 24V, this adapter is an easy solution to integrate it with your Phidgets system. The PSU2002 plugs into a VINT port and steps up the USB voltage as high as 24V DC. There's a trim pot on the board to adjust the power source to the desired level, and the source can be turned on and off by toggling the state of the digital output of the VINT port it's connected to.
