LED Digital Voltmeter Bracket
thingiverse
This bracket is designed for mounting a small digital voltmeter behind a Powertech MP3800 lab power supply. Despite the power supply's front analogue meter, I prefer greater precision with known accuracy. To proceed, purchase a digital voltmeter, such as the "0.36" LED Display Car Digital Voltmeter," available on eBay. Ensure its operating and measurement voltage ratings match your power supply's range. Then, print the provided STL file bracket set, assemble it according to the images, and attach it using screws to the GND and +ve terminals at the back of the power supply. Connect the black wire to ground, and red/blue wires to the positive terminal.
