Hey guys, welcome back! :)
This video hopefully gives you all the knowledge needed to build your own DC Electronic Load and more.
I made shure to provide you with an actual working, very basic circuit as well as showing you the prototype that I used to validate the circuit with. The prototype circuit went afterwards into my very first, portable and battery powered electronic load. That little thing is quite capable. Depending on ambient temperature it can handle between 25W to 30W for an infinite amount of time or much higher values for short term like up to 50W for 5 to 10 minutes max, again depending on ambient temperature. I go into some detail on how to properly rate your electronics load and try to give you an idea about the required cooling.
Also there is a quick preview on the next one I'll build ;)
