Discovery Power Supply (DPS3340)

Digilent’s Discovery USB Programmable Power Supply (DPS3340) is a three-channel variable DC programmable power supply that allows users to control the power provided to their external circuits. Providing both constant voltage and constant current modes with built-in readback sensors and optional tracking for the output channels, you can confidently power your circuits according to your requirements.

Driven by the free Waveforms software (Mac, Linux, and Windows compatible), the Discovery USB Programmable Power Supply can be used either as a stand-alone product or in combination with any of Digilent’s Test and Measurement devices acting as its own Tool within the Waveforms software – no external triggers or multiple instances of software required.
