USB energy has turn out to be ubiquitous — every part from telephones to laptops all use it — so why not your lab bench? That is what [EEEngineer4Ever] got down to do with the BenchVolt PD USB adjustable bench energy provide. That is greater than only a easy breakout for normal USB PD voltages, thoughts you; with adjustable voltages, SCPI assist, and way more.
The case is made from laser-cut acrylic, mounted to an aluminum base, not solely offering a weighted base but in addition serving to with dissipating warmth when pulling the 100 W that is able to supplying. Contained in the clear exterior, not solely do you get to peek in any respect the circuitry however there may be additionally a vibrant 1.9-inch TFT display displaying the voltage, present, and wattage of the varied outputs. There’s a knob that may modify the variable voltage output and navigate by the menu. Management isn’t restricted to the knob, thoughts you; there is also a Python desktop software to make it straightforward altering the settings and to open up the likelihood to combine its management alongside different automated check gear.
There are 5 voltage outputs on this provide: three fastened ones—1.8 V, 2.5 V, and three.3 V—and two adjustable ones: 0.5-5 V and a pair of.5-32 V. All 5 of those outputs are able to as much as 3 A. There are additionally a wide range of waveforms that may be output, blurring the traces between energy provide and performance generator. Whereas the BenchVolt PD shall be open-sourced, [EEEngineer4Ever] will quickly be releasing it over on CrowdSupply for these all for one with out constructing one themselves. We’re huge followers of USB PD gear, so be sure you take a look at another USB PD initiatives we’ve featured.
