3D Printer Power supply case / Siemens SITOP 24V-20A

thingiverse

To get rid of the noisy default power supply from my Tronxy X5SA I decided to get a Siemens PSU 24V@20A which has no fans inside. For this I needed to have a own small case where the PSU fits inside. Here the specs of the PSU: SITOP PSU100S 20 A Stabilized power supply input: 120/230 V AC, output: 24 V DC/20 A https://support.industry.siemens.com/cs/de/de/pv/6EP1336-2BA10/pi?dl=de I bought mine at eBay for ~50€. As per spec the PSU needs to have 5cm space from the bottom to allow the heat dissipate through the PSU to the top to avoid heat problems. I am running this thing now since three months without any problems. I am attaching as well the FreeCAD sources in case you want change anything. Please be aware that you are handling here 220V when assembling the thing together. The design is not made foolproof in terms of current protection! This is not to be placed near small kids or house animals. I have it in my basement in such a way that my kids can not touch e.g. the inside from the "open"! backside. The actual wiring is not provided here! In case you need help you can contact me. Actually at the moment also no power button is included in the design. I am planning to add this as well into the design when I have some time left.
