Modular PSU & Soldering station

Universal enclosure that can be used as a lab power supply, soldering station or combination of two.

Similar projects worth following

The goal of this project is to create a universal enclosure that can be used as a lab power supply, soldering station or combination of two.

Enclosure consists out of main body and front panel.

Main body is designed to be easily 3D printed in one piece without any supports.

Front panel is designed to be cut from 3mm thick tinted plexiglass sheet or 3D printed. On the front panel there are mounting holes for Ruideng DPS3003/5 power supply modules and/or Ksger T12 soldering iron controller. In general, a front panel for any combination or type of modules can be made, since outline dimensions are provided.

To power everything there is space for two Meanwell LRS-100-24 power supplies in the main body part. They each can provide 24 volts @ 4.5A. 100 watts of power per channel is enough for any soldering iron or lab power supply hobbyist may use. They each have a small voltage adjusting potentiometer that can be used to increase output voltage by few volts.

Use of quick connect terminals is not a must. Soldering will do just fine. Just make sure to insulate solder joints.


IMPORTANT:

This project uses main voltages that are deadly. Please use proper safety and follow wiring schematics and instructions outlined in video.

Before powering double check your wiring and before first use test output voltages(polarity and values).

I took a quick look at the files - do you publish the slicer settings you used for the enclosure? I'm most interested in the filament you used and resolution. Do you think this requires PETG or ABS, or would PLA work? (I wonder if the heat generated by the power supplies could potentially deform PLA?)

I plan on making a PSU/soldering station version once I'm comfortable enough with my printer to entrust a 2-day print to it.

Thank you for sharing such beautiful and functional work!

Nice project! This enclosure is beautiful, would love to get the fusion project.

Well done! I really like the design. Is there a link to Thingiverse for this? If the housing could be parameterized, it would certainly be a great fit for many projects. Best Ben

Thank you. There are 3d models attached in the “FILES” section. I posted previous versions on Thingiverse, but I gave up on it since the site is broken. They have bugs that go back a few years and are still not fixed to this day. Step file is included so everyone can make small changes to it. If someone needs, I can send a fusion360 project.

In future revisions I may provide a parametric defined model, but I can't make any promises.
