This is a protective housing for my 12V 30A power supply unit (model:S-360-12) which seals all the high voltage points and also adds a fused switchable high voltage input connector. I have also added two springy DIN rail parts which lets you to attach the device to a standard DIN rail. I found this great reliable PSU on [Aus3D.com.au](http://aus3d.com.au/electrical/power-supply/psu-12v-30a) website. I have also uploaded the Fusion 360 design file in case if you would need further customization.
