  • Dave takes a quick look at the spectacularly cheap $20 DPS series CC/CV modules from RD Tech.
    How to make a 30V 3A bench power supply with 1mA resolution constant current limiting and multi function display using a junk bin enclosure and a junked plugpack or old computer power supply.
    The DPS3003 30V 3A module in particular.

    If the current is reading a bit low, you can take some wire cutters and put a little crimp in the current shunt.
    That will increase the resistance and make the current read higher.

    Excited to see you trying these modules, but I think you should read the manual first. Setting the voltage is actually way simpler then going into the settings menu. Just pressing V or A and then pushing and turning the knob will enable you to quickly change the voltage. I have the DPS5015 and I am still very happy especially for the money, would like to see if it could actually go up to the maximum advertised power, I have only tested mine up to 250w.

    I’ve been using the RuiDeng BPH3205 on my bench (and on my channel) for a few months and it works extremely well as a buck boost on my 12 volt lead acid batteries. It’s worth noting you can adjust the voltage and current output without going into the full setup menu by pressing the V or A button and then using the rotary encoder. Great value as you say.

    I've had the DPS5005 for about 6 years working great. The first few years I powered it with an old dell laptop charger at 19.5v. About 2 years ago I got a 48v brick for it and have loved it the whole time. The case they sell to go with them includes an extra cooling fan with it's own daughter board mini power supply off the input.

Bought a load of stuff last year for not much more than postage and with the electronic junk we harvest from the scrap pile, my little middle school student electronic club has parts and such to learn and tinker with. Kids still love to learn about, tear apart, and up-cycle electronics, just as we did as kids- warms my heart. Keeping the electronics bug going for another generation ! Be Well !

  • @peterschmidt9942
    @peterschmidt9942 Před 7 lety +1

    Dave, I've seen them before and contemplated using them however when you start counting the cost, they start getting quite expensive (up in the territory of actual lab power supplies). Say you wanted a 0-30V 3A PS. This module is about $32AU + supply to run (36V 3A) $15 + ABS case $15 =$62 (never mind the bits and bobs). You can get a bench power supply on ebay for $60 delivered (V/A display, steel chassis + warranty). Fine if you have a spare PS to run it, or have an abundance of cases laying around, or you want include a PS with another project for some reason. These are OK when you're taking

    I have the 50V 15A version. 2 of them actually, and they work great. When I got the first one, I put it through a stress test, drawing 15A at 12V with 54V input, for an hour and it survived flawlessly. That is when I decided to order another one. Highly recommended for anyone who needs a relatively cheap and reliable CV/CC bench power supply.

    Hi Dave, these are very good performers. I made a few different combinations up recently, one as a portable battery powered bench (field) supply running a 3s 5Ah lipo into a boost regulator and the appropriate module giving 0-30v and up to 5A.. fully portable, it works brilliantly.
    Another is the 15A version backed up with a 350W smps which I use to charge a 200Ah 24v lead acid EV battery, and it does full load (300W) for hours, and has done dozens of charge cycles with that vehicle. It runs pretty warm but no runaway.
    The last one is a brute with a 750w smps (48V/16A) and it really delivers. For the money no other option comes close.

  • @turboslag
    @turboslag Před 7 lety

    I have the 12 amp version and have fully loaded it with an electronic load, for about 8 hours, without a problem. Max temp on the heatsink was about 50 deg C in an ambient of about 25 deg C. Biggest problem was finding a TX big enough to provide the DC input but I lucked out and was gifted a DC pack from a scrapped MRI scanner! That had a huge toroidal TX on it, with some hefty bridge recs and smoothing caps! They are really nice little modules and even if they turn into magic smoke after some abuse, who cares at the price!

      The sad thing is that the seem to apply those stickers without ever powering on many (most/all?) devices as I have received other China export products where the input or outputs of a power supply were clearly bridged across with solder, so a dead short, yet still carried that silly QC sticker!

Grabbed a 60v 6.7a psu off ebay for $30 (which has a voltage adjustment range of 54-66v, so I simply set it to 54v) for a complete setup that takes advantage of its full potential. They're manufactured by Ruideng. The housing is labeled with both the RD logo and "Hangzhou Ruideng Technology"

    i was putting in my latest eBay order when I noticed something similar in my recommendations, so I splurged for I think the $15 and I have been so happy with it.
    I went the even simpler route and got some short 2-3" chunks of wire and some "M" cable connectors. combined that with some custom alligator breakout clips and everything else using the same connections I have a very modular system.
    I actually soldered to the connectors in case I wanted to use the screw terminals with a higher gauge wire or other projects.
    I also picked up a LED work light that works off of 12V and because everything uses the same connectors I can just put this in line and now I have a dimmable LED light when needed.

They are amazing, having buck-boost gives u 6-40v input 0-30v output, you can plug it into anything you find and get the power you need. Been using them for a year now every day.

    I have a 35V 15A version of one of these hooked up to a 36V 20A DC power supply. Works great. It is a bit noisy, but I just add extra filtering to any sensitive projects. I haven't tested it below 1.5V, but it does give a full 15A at 1.5V.

  • @PlaceholderforBjorn
    @PlaceholderforBjorn Před 7 lety +2

    Would love to see you test those who have higher current and voltage. I have wanted you to test these since I found them. I have built my own and is quite happy with it.
    The only problem I have is to find a good case that can fit the plug pack, the module and a extra fan but isn't to big.

    I have been using a 50v 15A one for half a year or so, it's really rather nice. Have not tested with more than 400W, but it does that admirably while staying fairly cool (65*C or so), yet a bit loud (though I dont think that was the max RPM on the fan). Powering it from 500W 48V power supply that I build into the same case as the module for a nice self contained unit. Overall really nice pieces of kit. Got it for 36$ on Ali at the time.
    Also you can press the up and down arrow to adjust from the main screen, that's why they are marked with V and A.

    I used their buck-boost converter (DPH3205) to build a bench supply. I had a 12V 13A Cosel power supply lying around which serves as input to the buck-boost converter. Very easy to build.

  • @JWH3

    I like the idea of putting one in a decent case. Showcasing some ready made stuff from Ali could be fun. Add a pre built neo pixel LED fader for the hell of it. Takes minutes to build that stuff.
    Give away a few decent looking ones in a little raffle or contest. Pimp the eevblog logo a bit. Fun and practical, and people love free stuff :)
    The scope of kits available on something like Ali is unbelievable. Modules of allll kinds, mini scopes other fixed power supply modules ect... Ect.. the possibilities are endless, could probably do videos like that twice a week and have material for ages. If you can find a place to store it all :)

    Ive got one of thse little module units which i run off a 18v Li Ion power tool battery. Also added a little beeper set to 15v so i dont run the battery down too much. Works as a great portable little power supply!

    • @ethanpoole3443
      @ethanpoole3443 Před 7 lety

      TheColinputer If you are using the Ryobi 18V One+ Lithium Ion battery packs then they have the necessary protection circuitry built into the actual battery packs themselves since the battery packs had to maintain backwards compatibility with their older NiCd battery packs. So if those are what you are using then no other protection is required. But I can only say that with certainty for the Ryobi 18V One+ battery packs, though some other brands may also build protection into their batteries (as opposed to the tool).
      I occasionally disassemble their battery packs to incorporate into robotics projects since their batteries have the protection and balancing circuitry built in and all that is required for charging is a 4-pin connection back to the charger (and you can use an empty battery shell to interface with an unmodified charger. But that gives me a 5-cell battery pack that ranges between 18-22V, depending upon charge state, for driving motors and a source of power to downregulate to 3.3V and 5V as needed for the sensors, control circuitry and microcontroller boards.

    • @TheColinputer
      @TheColinputer Před 7 lety

      I use Makita mostly which dont have any cut off in them. But i also have some AEG which do however its at about 13.5v and i also have Milwaukee but i honestly am unsure about them. I just got the little USB phone charger add ons for each brand and cut part of the plastic to fit an XT60 connector. Then just use that to plug the power module into them.

    I put two DPS5005 (sharing a 24V meanwell supply) and a DPS5015 (with a separate 5A 24V supply) in a box for a three-channel supply, and with the separate input supplies it functions as a split supply too. Very happy with it! Also worth checking out github.com/kanflo/opendps but TBH the stock firmware UI doesn't bother me too much. I think I'll update them if I find myself wanting to control or data log over the UART.

  • @petec6690
    @petec6690 Před 7 lety

    Very interesting little device. I currently have some 1970 era power supplies I've been thinking of modifying into something as useful. The ones I have contain Fero-Resonant isolation transformers. Those coupled with AutoTransformers to get the range of voltages from 0 to 128 VAC or 135 VDC, but no current control and no readout. Glad you did this video FIRST. I can still use the cases these old supplies are in and cut new holes for the modules. No doubt I'd opt for the higher voltage and power ranges just simply for the sake of having something I might need (if ever). I certainly don't need 135 VDC, and I have virtually no idea how much amperage these oldie's are capable of. So it looks like this will be a "Soon to tackle" project. For now, I still have to build my "Marble Machine" for my grandkids and a custom hand made picture frame made from Juniper we cut down two years ago. Busy little beaver here.

  • @InfernosReaper
    @InfernosReaper Před 7 lety +1

    Bound to be better than my ghetto bench power supply built from an old computer power supply. 3.3V, 5V, & 12 by default, but I can hook up a cheap adjustable boost converter for other options & check the setting with the multimeter. I've been considering revising the design to have a dedicated adjustable output with a sub $10 multimeter display. I've also been toying with the idea of connecting all the unused 12V lines to a car power outlet so I can power more power-hungry devices.
    If the supplies in this video are decent, that might make my bench supply obsolete

    I have 12 of these, all different models. Not an issue yet with any, even the DPS5020 50V @ 20A with USB & Bluetooth connection to A PC running their software. They're awesome. Just grab a 48V powersupply (with adjustable voltage, most I've used go over 50V, or something higher but under 60V If I remember right) DPH is great with Buck/Boost. The guy who owns RDTech is a great guy. Very friendly and my packages via e-Packet arrive to Canada (West Coast) in 1 to 3 weeks in a nice styrofoam container. I don't know if something has happened to the quality though, none of mine look like that. They're clean and no solder issues. AliExpress is the official store.
