Riden RD6006 Power Supply Part3

[@onerka69]

I found that even though the iOS app is very simplistic compared to the front panel or the PC app, it’s nice to be able to set a battery up for charging and then go somewhere else in your house and monitor it while you’re away.

[@jontscott]

That is a neat power supply. I think I will have to get one and try it out. Battery charging seems nice, does it only do CC CV charging for lithium batteries or can it also do -dV / -dT charging for NiMH too?

[@JerryWalker001]

The battery charging is very basic. It is really only a CC/CV charger. You have to set the maximum voltage first and it just charges to a terminal voltage. It does not do any peak detection although it could still be used to charge other battery types. As far as I can determine the only difference between the normal output and the battery terminal is a blocking diode and battery present detection. It does work but I would only use it with batteries if I wanted to investigate battery performance (which I assume is the intention). It seems to be a very good supply so far. I carried out other tests (not recommended) such as connecting charged caps etc to the output, inductive loads, shorts etc to see if I could kill it and so far it has survived. I can see it becoming a well used supply in my lab as it is quick and easy to use and combined with the high output makes it very versatile. I am hoping that they change it so that the output turns off when a memory is selected as that is (in my opinion) a major flaw.

@@JerryWalker001 I think you make a good point that adding an option to disable the output automatically on memory setting change could be nice for some cases. While I don't have one of the power supplies yet to speak from experience, I like the idea of being able to smoothly change from one voltage to another without power being disrupted. I would think the warning to confirm the voltage/current is sufficient to prevent accidentally applying too high a voltage in most cases.

[@JerryWalker001]

I still think this is a very bad part of the design. Apart from the fact that the warning can be turned off it is way too easy to hit the wrong key. For example hitting the 8 instead of 9 could select entirely different voltages (maybe 60V instead of 3.3). There is absolutely no advantage. If you want to switch smoothly between voltages then simply enter the voltage you want. Eg to switch from 5 to 10V then simply enter 10V and press enter.

Hi Jerry, thanks for the riden series very informative. I have just bought two of these I am also impressed, just wondering if like my Siglent you can set a "time period " say for battery charging etc in the memory function.

[@JerryWalker001]

I am about to build a second unit using a linear primary power supply and I will be posting some videos on this process and also on how the two units compare. The battery charging is very basic so no capacity limit or delta peak detection. It just runs in CC mode and then CV until the charge current drops to less than 10mA and then it turn off the power. I doubt I would use this for actual battery charging. This function may be useful for initial testing of battery control systems. You could use the 'external' temp sensor as a battery pack sensor and the supply would then shut down if the pack gets too hot.

Thank you for deciphering the menu.

@5.15 : You can put a piece of transparent tape on buzzers to lower the volume. :) Really handy. Quick fix or low-tech - But it works great.

[@JerryWalker001]

I use adhesive backed foam tape. It makes them even quieter. But only when I cannot turn them off completely. I think I mentioned this in one of the videos.

[@ebzor]

@@JerryWalker001 Great. I imagine that! Have to try that out sometime. I must admit, that this is the first time watching one of your videos. I won't go into to much details, but this seems to be a good deal for hobbyists, or professionals within different professions. Regards, and thanks for quailty content. *thumbs up*

[@sheetalmekhale]

Are you planning any tear down of RD6006?

[@JerryWalker001]

I could show it but there is not really much to tear down. Just a small pcb and a display.

[@sheetalmekhale]

@@JerryWalker001 It would be nice to know the ADC they have used to for measurement, the DACs used for adjustment. also details about the the main processor etc. :) it would give an insight in product

[@JerryWalker001]

I will be constructing a second unit using a linear supply so I will do a mini tear down of the RD6006 as part of that.

[@Dextermorga]

Hmm I bought one today. RD6006w + case + recommended power supply = $130 :( from official store with tax 8.25%. I was hopping to get one for $100 but no chance.

[@JerryWalker001]

Yes that is about what I paid (£100.00) The prices do vary a great deal.

[@megacharizardx9474]

Can you give me a link to the power supply please

[@megacharizardx9474]

I am not talking the RD6006 model

[@Utube2Itube]

It’s not good to start off a Li-ion battery charging process with a constant voltage mode, you should start with a constant current mode and not exceed a 1C charging rate, and then finish off with a constant voltage mode if you wish to really top charge the battery and compensate for the internal losses you had during the constant current mode. Not blaming the video creator here, but the software should not allow to start off in constant voltage in the battery mode. It’s asking for too much battery knowledge from the user.

[@JerryWalker001]

As I said in the video I would not use this for battery charging.

[@pradipkhare]

This is what a difference between Dev Jones, he could have entire subject in a single useful session, rather 3 useless parts....

[@JerryWalker001]

I think my videos are more useful than your comment. I was asked to show more detail than Dave had shown which is what I did. Dave did not show the building or other aspects that I included. This may not be something you are interested in but others are so your comment is not really very helpful. If you did not like the first part then perhaps watching the following parts was not the best option for you. I tend to make videos which include content that I have been asked for. If you prefer Dave's videos then I can understand that as I also Like his videos.

[@pradipkhare]

@@JerryWalker001Hi Jerry, my apology if my comments hearted you, but it was not meant to be negative but to tell you that even Dave provides a detailed explanation but focuses more on real subject - which we all can learn upon. Therefore, you may wish to hide things, either those are very obvious like screws tightening/opening or not required about a general features of the a power supply - which we all understand what it being a SMPS. Once thank you for producing a detailed video and continue doing so, however, if you feel that my above comment can be helpful, then I am glad, if you consider those. Season's greeting.

[@JerryWalker001]

I have been SPECIFICALLY asked to cover these things by others and while you may not find them of interest then obviously others DO. There would be no point in me simply copying what Dave is doing so I will not. If you prefer his content then watch his videos instead, no harm, no foul but leaving insulting comments on my videos is childish, just don't watch. These videos take a lot of time, effort and money to create and UNLIKE Dave I do NOT get paid to make them. I make them at my own expense to try to help those who may be interested. If you are not interested and I have nothing to teach you then don't watch.

[@pradipkhare]

@@JerryWalker001 If you don't want criticism or comments and cannot take it in right spirit, please switch off that option, so that no body provides their feedback or comment.

[@JerryWalker001]

If you do not want responses to your comments then do not make comments. Your comment was a pointless insult. If you do not know the difference between a useful comment and a childish insult then do not make comments. It was certainly not a critical comment (lookup the meaning). Most people make comments that have some meaning, even if they are negative, but you did not and you are unable to understand why your comment was pointless. I am more than happy to accept critical comments unless they are nothing more than insults. You did not provide any feedback and I fail to see what 'spirit' you intended other than an insult and your arguments only go to support my initial reply to you. I suggest you look up the meaning of criticism so that you can avoid just insulting people. I have now explained to you TWICE that the content you complained about was requested and you are unable to accept that the world does not revolve around you. You are not forced to watch my videos so why watch 3 just to complain that the content is not what you personally want?
