Voltlog #108 – 150W Electronic Load Review

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.

Voltlog #82 – DIY Adjustable Analog DC Electronic 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:

Voltlog #61 – Dummy Load Special

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.

Voltlog #39 – 60W Dummy Load Reverse Engineering

In this video we’re discussing the dummy load again but this time I reverse engineered the dummy load schematic and I discuss it’s basic theory of operation. Check the video description for a link to the pdf schematic.

Voltlog #38 – 60W Dummy Load Review

In this video I am doing a review of the recently purchased 60W Electronic Dummy Load. I go through the different operating modes, a short stress thermal test and in the end I am presenting a conclusion whether or not this is a good buy.
