PocketPower25  (models PP25P and PP25N)     by Versalent   Home

Tiny Adjustable 1.75W USB Power Supply that Fits In Your POCKET!

Provides precisely controlled DC power up to +25 Volts DC (PP25P) and -25 Volts DC (PP25N), and up to 350mA without the bulk and weight of a bench power supply. High efficiency due to the internal switching pre-regulator, and quiet, highly regulated output due to the subsequent linear final stage. USB control software offers single-screen management of multiple supplies with optionally assigned tracking. The available DLL allows for your own integration into production or lab processes all at low cost. image here

DESCRIPTION

       PocketPower25 is a 2.25" X 2.4" X 1" module which provides up to 1.75 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/350mA 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 using a linear output stage. To use the limited USB power efficiently, that linear output is preceded by a tracking switching supply. This pre-regulator provides the efficiency while the linear stage provides for excellent control, load regulation, and quiet output voltage.
Software Utilities available for download

PocketPower25 is supplied with a 3.5mm X 1.3mm output cable with test hooks for connection to its load. An optional and very flexible USB cable with micro USB connector is available separately.
