If you’re looking to construct your benchtop power supply, you may need DIY instruction from the Supplier. A compact and flexible Arduino power supply can provide between¬†4-to-40 Volts¬†and outputs anywhere between¬†1.25 up to 36 Volts¬†with a maximum output of 5 amps. This¬†DIY benchtop power source¬†is fitted with the XH-M401 module as well as an XL4016E1 DC-DC buck converter that handles voltage regulation, providing electronic engineers, hobbyists, and developers with a reliable power source and a range of voltages.

Complete instructions on how you can make your personal Supplo portable power source for your bench with an LCD-based graphical display have been posted on website earlier this week, thanks to the Settorezero team composed of engineers and developers. The project is classified as an advanced build that will take about two weeks to finish. The Supplier uses the Arduino Nano R3, and all the electronic components are housed inside a 3D-printed case that is available on the official page for the product.

Supplier DIY power supply for a benchtop

“Supplier is a Quick & Dirty PSU (Power Supply Unit) constructed using a variety of readily available breakout boards such as an Arduino Nano (or an Arduino Nano Every) and an LCD with graphical graphics. The power output is supplied by a DC/DC Buck Converter built on the XL4016E1 device, with the possibility to regulate the production voltage.

Concerning the electrical inputs, we suggest using an external PSU with 20-30V like the ones that are used by laptops and old printers. This method is safe and affordable; however, you could decide to install a larger enclosure and add your transformer, diode bridge, and capacitors with lots of cautions. We made use of this project to reuse some printers PSU with an output voltage of 24V. .”

“Arduino doesn’t manage the buck converter component, and it only detects the output current and voltage with the current sensor. It then displays the values on a screen. Power values are also displayed. An additional gauge analogue can display the voltage, current or power values, giving a retro look to the graphic.

The power output of the banana socket is fed through a relay. Arduino removes power by sensing an external pushbutton or alarm-related events (short circuit/under voltage, overload and overload).

A separate DC/DC buck converter is set at 5V to power the logic, drawing an input directly from the variable module. In the future, you could also port this 5V into the panels (making modifications to enclosure ).”
