Another afternoon project. Some time ago I was working on a 80 watts 12-to-36 Volts DC-DC boost converter. Not one of my most successful projects but anyway.
So I needed some kind of load but my home made constant current dummy load can only handle 20-something volts. A few 100 ohms 15 watt resistors were just what I needed. So I took 6 of them and made a simple, single-sided PCB that holds the resistors as well as 6 switches.
The resistors are upright and have a bit of an air gap between them. That’s important, they get incredibly hot with 36 volts accross them. I know, I had to learn the hard way 😉
Together with the aluminium front it has a nice weight for its size and with it’s silicone feet it sits firmly on the bench.
Good project
could you send me the pcb layout and the list of components? thank you
sure, you’ll get an email
Hello
Could you please send me the pcb layout and the list of components?
Thank you
Can I get a pcb layout of this too? Thanks.
Just sent you an email…
Hi Azerimaker
Thanks for sharing the link.

This looks exactly like the dummy load that I can use for testing my own power supply. Simple and effective!
Could you please send me the pcb layout? It would be greatly appreciated.
Best regards

Hi Jonny, not sure if I can still find the files of so long back. I’ll see what I can do.
