DESCRIPTION
PocketPower25 is a 2.25" X 2.4" X 1" module
which provides up to 1.25 watts of very controllable positive/negative DC power. It derives all power and control from a standard USB port, so works with any desktop or laptop computers with standard USB ports.
Manual available here
Voltage and current are precisely controlled and programmable up to +/-25V/250mA using the supplied Windows application or DLL so multiple devices can be configured in a tracking configuration. The outputs are NOT isolated from the USB ground, so there are separate models to provide positive and negative voltage. PP25P provides positive voltage, PP25N provides negative voltage.
How Does it Work?
PocketPower25 provides precise and widely adjustable DC power by combining a switching pre-regulator with a linear output stage. Because USB power is very limited, the pre-regulator provides for efficiency while the linear stage provides for excellent control, load regulation, and quiet output.
