- In this video we explain the module, view components under magnifier, view datasheet for each components, all settings are shown with example. We then show you how to use memory presets and then wiring is explained. The test will start with input of 60V and we go to 48V, 36V, 24V, 19V, 12V, 8.4V and 6V and the output will be tested with all the standard voltage 48V, 36V, 24V, 19V, 12V, 8.4V, 5V and 3.3V. In each voltage we try the current at 5V, 10A, 15A and 20A. In each test we show also the input, output current and voltages and power so you get a better idea and efficiency is shown.
We then show how to calculate and understand charge voltage and current to charge batter using this module.
Then we move to downloading and installing PC software to control and monitor voltage, current and power for this module and we also install Android app and show you how to use it.
The ripples are shown under different voltages and currents on oscilloscope. And finally conclusion is stated.

new fan says thank you, all your videos are very helpfull, :)
Glad you like them!
Thank you very much always the best and very detailed informative video
Best regards from Philippines 🇵🇭
Glad it was helpful!
You sound like Gru of Despicable Me. Loved the review keep it up.
LOL. When reading your comment, the RUclips Studio AI suggests that I should click on one of the 3 pre-typed texts to reply. 1- "Wow thanks" 2- "I am" and 3-"I was".
A very thorough review. I would like to see a test for stability in terms of how the power supply handles a dynamic load. A power supply that has poor stability results in ringing as the load steps up or down. This can cause issues for the equipment such as amateur radio transmitters as the power swings are very high on CW or SSB.
I have started to look at the stability of power supplies. The most important is a programmable load capable of dynamic loading. I have a Tenma 72-13210 electronic load that cost about AU$ 350 from Element 14. The other gear is an oscilloscope and a current probe. Using the oscilloscope allows any ringing to be seen under a dynamic load. Regards Drew VK4ZXI
Actually I wanted to do that type of tests but so far I have not seen encouraging signs from viewers. 94.6% of viewers are non-subscribers and that has great impact on my channel. Subscription is stamp of approval for a channel and and videos of a channel with more subscribers will be discovered more. I will keep your suggestions in kindle for future video and even I make make video on this module with different current and voltages in different intervals of milliseconds or seconds . My electronic load is programmable and execute those type of load. I will see if time permits. Cheers
@@WattHour It would be interesting to test a number of power supplies to see how well they perform with a dynamic load, especially if some bad ones were included. Many amateurs are interested in repurposing server power supplies but I am not sure how well they would perform with a dynamic load.
I don't think many people are even aware of the problem. My understanding is that it is mainly a problem with switching supplies because of their more complex feedback loop but it would seem a potential problem of any regulated supply, linear included. I believe it is possible to improve a supply's performance by adding more capacitors, at least up to a point.
The Texas Instrument application note gives a good explanation. www.ti.com/lit/an/slva381b/slva381b.pdf
Would also love to know that. Looking to power my kenwood ts2000x amateur radio station with a 48v nominal lion battery
Thank you!
You're welcome!
Hello sir, thanks for the good work, can i use this to control charging of my 3s 12v lithium battery, I leave it to run the circuit permanently?.. I I set the output to something like 12.4 and hook it up on the pack of lithium batteries that have BMS.........
I'm having an issue with a feature of this module, I made a power supply for it with an old 50 volt transformer. The problem is that the open circuit voltage is 69 volts and this module won't latch on if the voltage is too high, do you have any suggestions?
My first thought was the rip a couple windings out of the transformer, but that seems like more effort than it's worth. And there is the risk of damaging the transformer
I have two of these modules in the power supply I'm building, so it would be worth it to me to replace components on the board over buying a 60 volt variant. I did look for a 60 volt variant but I couldn't find anything in the same form factor
Can the output be put in series to increase the volts out?
No and yes. Yes if you use separate input power from power supplies that does not share a common Ground. No if you use the same power supply for both.
Can it be used to charge batteries?
Yes . Use chapters to jump
1:02:38 108%, should get 100 of these and connect them to each other and make an ARC reactor. 🤣🤣🤣
You always record interlaced video, which really not good for multimedia. Check please your camera and try to switch it to "progressive" recording mode.
It is all progressive. Besides I don’t see anything low quality. It is encoded with heights bit rate and quality. Show something that does not look good so I look at it. Thanks
Ytb cannt fast handle long video. You have to wait a minute.
@@WattHour listen to me please, I know what I'm saying. For example on 0:00:08 when your hand goes up - it's cleanly visible that interlacing is there !!!
@Oleksii Zagorskyi I appreciate your comment. the video is coming from a Sony Camera's output. it is recorded on my Nija 5 recorder www.atomos.com/products/ninja-v which does not have any interlaced/progressive settings except different codec and compressing with frame size. It might be my Sony camera output by default it must be low quality. I will look into another camera. May be this is time to move to full 4K. Thanks
@@WattHour it's possible that the camera you use to record these scenes (on top of table etc) has only interlaced video output or recording, that's why it's there. In such case you should de-interlace it first in your video editor. There are such options.
