Fig. 1 - Electronic Resistive Load - 50A Power Supply Test with PCB |
You know that moment when you have a power supply to fix, you do the service and the supply works, but you don't know if it will support a large load?
I came across a problem like this, and I decided to make my own resistive electronic load, and share it with our subscribers, and for you who visit us, welcome!

The PCB - Files to Download
In Figure 3, we provide the PCB - Printed Circuit Board, in GERBER, PDF and PNG files. These files are available for free download, on the MEGA server, in a direct link, without any bypass.
All to make it easier for you to do a more optimized assembly, either at home, or with a company that prints the board. You can download the files in the Download option below.
