Description

PDF

This model is intended for makers building electronics to include in their design process, as it removes the extensive process of measuring this part to fit when designing your wonderful lamps/clocks/etc.

It is a replica of the PSU sold on Ali Express as the “AC100-220V TO DC5Volt Power Supply Transformer Constant Adapter Driver For 5050 RGB Led Light Strip And AU EU US UK Plug 2-60A”

This is the 4A version you can find here, which needs to be selected as it defaults to the 2A version. You will find copies all over Ali Express with different names and part numbers, but this is the one I modelled it from.

I have added all the details that will matter to you as a maker. If you would like to view the model in colour in your browser with optional AR, this is available directly at the Shapr3D viewer here.

These power supplies can have small variations in how they are assembled depending on how they were screwed together at the factory. Just do a quick check to make sure all the holes are in the right place.

Also, I would love to see any designs you create in the makes section, it will give me motivation to add more. Enjoy!

Safety

Please ensure that you have relevant electronics/physics education before considering designing a device, or building this into your models. Electricity can kill and poorly designed devices are a fire hazard and a danger to life.

The picture instructions on the Ali Express page do not show the earth screw terminal connected. If you did not consider this, please do not build a device yourself (see above) as you should definitely earth it.

As well as all the electronics calculations, please also ensure proper ventilation and/or cooling as appropriate.

Finally, I do not vouch for the safety of any electronics especially from Ali Express. All the PSUs I buy are individually bench tested upon arrival. None have failed yet, however please be safe.
