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:
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:
This episode will be taking a look at different dummy load models, these are all purchased either from ebay or from banggood so they’re easy to get and inexpensive. I just wanted to show them together and make a bit of a comparison just to help you understand the differences between these models so that you can choose the model that will fit your needs best. I have 5 dummy loads in total, starting from $5 a piece up to $20 a piece.
There might be slight variations of these available for purchase , some might come configured for different maximum power dissipation, some might have enclosure but those are all details that you can figure out on your own. Today I’m just going to point out the major differences and features of each one.
In this video I do a quick review of a 5 inch LCD TFT Monitor With 2 CH Analog Input. This module was sent to me free of charge for review by gearbest.com. The module is based on the MST703 video decoder and if you want to know more about this chip check it’s datasheet in the links from the video description.
