At the end of last year, I wrote about a 2,400 W electronic load. At the time, it was essentially a pilot unit ordered by one of my customers. After the New Year, I ordered several enclosures designed specifically for this version and decided to take it beyond the prototype stage—even if not into full production, at least to the next level.

This story began a long time ago—I think more than a year ago, though its roots actually go back to 2023. Today, I’ll show you what it all led me to.

It all started when I ordered a couple of CL24 loads a while back. They sat around for a while, and I thought, why not build a couple of complete devices around them? So I thought about it, thought about it some more, and did it.

Not long ago, I posted a couple of reviews—one of a voltage converter and one of a power supply—and mentioned that I’d bought them specifically for a new version of one of my projects: a battery tester. Today, I’ll tell you a little about it.

I've already explained how to turn an ordinary power supply into a charger, but for a long time I couldn't shake the thought that a charger should work more properly. Then I came up with the idea of making one that was not only proper and simple, but also based on the adapter board I'd already shown.

Not long ago, I featured a new power module in several of my videos. You may also have seen the backstory behind it in a few other reviews. I can now say that the project has reached a kind of logical conclusion. Though, to me, a conclusion is really an opportunity to improve on what came before and start something new, perhaps even more interesting.

Not long ago, I posted an example of modifying a Mean Well UPS using my own board. That time, I used an older version of the board, which had some drawbacks due to the simplicity of the circuit design. Today, I’ll show you the new version of the board, which addresses the shortcomings of the previous design.

About a year and a half ago, I wrote an article about a homemade (well, almost) electronic load, and I’ve finally decided to take the project further.
