Today we are taking a look at yet another electronic load. I found this one on Aliexpress, I think it’s a rather new model so let’s see what it can do.
Here are links to the 150W and the 180W version of this dummy load:
I never expected this electronic dummy load to be so bad because I kinda liked the way it’s built and how it looks. Unfortunately it’s way out of spec on the measurements and also has some firmware bugs.

Welcome to another Voltlog, today we’ll be taking a look at what I’ve been receiving in the mail recently. As much as you guys like watching this stuff, I also like getting all these electronic modules from China. I find it interesting every time I get my hands on a new circuit.
As always I appreciate feedback and discussions in the comments section below, please let me know what you think and don’t forget to like the video, that is always a clear indication of what kind of content you guys like seeing.
Here are links to all the items shown in this video:
In this episode I am building an analog adjustable dc load with parts easily obtainable from ebay and banggood. The advantage of such a dc load is that you can understand how it works, modify or repair it if necessary far easier than you would with a digital one. I was able to push mine up to 60W dissipation, but it is recommend to stay under 50W to protect the mosfet.
Here is a list with links to the parts used in this project:
Sometimes, when I have some spare time I like assembling these cheap kits coming from China. Today I am assembling an LM317 adjustable power supply kit complete with voltmeter. Unfortunately they sent me a wrong resistor value so the kit didn’t work as expected but I was able to fix it in the end.
Today I’m going to be building a complete DIY analog bench power supply. The actual analog power supply kit (0-30V 0-3A) that I’m going to be using, is this one, it was shown and assembled in voltlog #8. Besides that I’m going to be using this plastic enclosure which I think is quite nice and perfect for such a project, this one can also be found on banggood and there will be links in the description for all the items used in this build.
In this video I power up the dc-dc adjustable step down power supply with LCD I got from banggood.
