Thank you so much for the response, I figured that out after I watched your video and you referred to the right side as a 12v out, light bulb went off for me 👍🏼
an update i just modified the power supply you are right just clip the 2 jumpers and remove the screw to isolate but with a twist. instead of putting paper and hot glue i used another screw and ripped the stud from the case through the back of the power supply case and using a nylon riser and screw i placed a nylon hexagon riser stud under the corner of the board and used a nylon screw to hold the hexagon stud in place. nylon is a form of plastic and plastic DOES NOT CONDUCT ELECTRIC so nylon screws work perfect for insulation. the same electrical warnings still apply. once you unplug the power supply make sure to wait a minute for the capacitors to discharge before opening up the power supply and using multi meter test the heat sinks to ground and each other before going any further to be safe.
Hi Tony, i just got a ISDT 20 charger, max input current 35A, charge current 0.2 to 20A X2, max charge power, 500W X2. I'm going to use x2 DPS-1200W FBA 100Amp PSU's to power it. There are some differences from the PSU'S you show in your video but that's not a problem. Would you kindly help with a couple of questions? Is there a way of discharging the capacitors to make them safe? Also, considering the ones I'm using have more power, what jumper wire should I use to link them, AWG 10 or 8? Final question, I have very little knowledge of these things so please forgive me if this is a stupid question! I assume the charger will only pull the current it needs and it uses an XT60 input so will AWG 12 gauge be adequate to connect to the charger?
Hi Tony, question i have a case built and i use a imax mini 60w charger and i do use 6s 5000 lipos, would i need 1 or 2 of these to get some quick charges like what i just saw in this video? oh and BTW....very good and clear precise informative video! no confusion at all on what needs to be done. thanks in advance!
What I really need is an adjustable voltage and adjustable constant current circuit with a display any thoughts gang I'm going to be using it for a bench supply for a lot of Differant things thus the reason to make both adjustable even at full output
I got probably 20 of those meters. LOL! Used to go there a lot and that was the only free coupon I was interested in. I'd give one to my wife and kids so sometimes we'd leave with 3 or 4 meters. I am not a hoarder...no, I refuse to believe it.
Hi, I have this same power supply set up, my question is....how can I connect two more external cooling fans for my charge case to my power supply if possible, thank you.
I just connect them up to one of the PSU's (12v source) that way when the PSU is on, the fan is on. This is the way I have it in my setup with just a standard 80mm fan from a computer case. Hope this helps. www.Rc-Help.com
does the charger require a switching power supply? can you get away with using a 60 hz transformer say for example rewinding a microwave transformer to put out 24 volts ac at 60 amps and then using standard diodes and a large 35 or 50 volt 50000 uf industrial sized cap or 2 series wired audio capacitors? is there a back ripple or something that could destroy the diodes and capacitors of a conventional 60 hz power supply?
Tony, If someone wants to connect 4 of these power supplies in series to create a 48v power supply, how many (and which ones: example the first 12v or first, 24v second and 36v third etc.) would require the DC ground modification? Thank you for your time and efforts to share this useful information.
I have completed a 48v power supply with 4 of these. Only the first power supply remains properly grounded in the series circuit. The remaining three require the ground modification on the dc side.
i have a question, what if i want to wire the power supplies in parralell instead of 575 ones 1200w ones , 2 of them. do i still have to float it in order for it to be in parralel??
nice vid.do you have any compaq power supplies? i have one that came out of a server .the connects are basicly the same except i have more'.any suggestions?
You shouldn't need to float a ground if you are just wiring them in parallel. Stranger things have happened though so do this at your own risk, but with no positive going into a negative terminal, I think it should be fine.
Ebay, amazon. Ask IT people at your work, may be they trash some old servers. Also quite powerful power supplies could be salvaged from network switch.
purchased mine from eBay. You can get newer server PSU's that are already 24 volts output and 1000w for cheaper. Just do a search for "server 1000w 24v psu" and you should get a ton of results. www.Rc-Help.com
I think Yes, but not 100% sure on that. If one goes bad and you have them in series and they are not of the "floating DC ground" type, then you will get an outer case with full mains voltage going through it. I would definitely have someone that knows these things look them over to make sure they are safe.
+RcHelpDotCom at 11:29 the black and red wires how are the soldered to the prongs? Doni solder both onto a 4mm female plug? Also i seem to be having resets every once in a while too my charger be charging then it will reset back to not charging. Do i have to make thst internal change if im only using 1 power supply?
I'm having trouble finding pin diagram for 1500W Fuji Electric CA05958-1020. Picture link below. Can you help? Just need to turn it on and I can do from there. Thanks. i66.tinypic.com/352q81c.jpg
For some reason, it moderated your comment. I had a look for that PSU and I could find nothing on a pinout diagram. If you already found one, fantastic. If not, I think the only way is to actually pin it out yourself, which is a PITA. If you can find the server that this PSU goes in, it could make it a little easier, well sometimes it is easier. www.Rc-Help.com

Thanks a lot for making this video! I just got 2 of these today and couldn't figure out why they didn't work in series.
Saved my day! Thanks! :-)

Great video, works really well for me. Did you get around to making a video on making a case for them? This saved me loads of money
Thanks alot from germany =)

Great video! Thanks. If I were to build this wouldn’t 24v be to high for most chargers? Most seem to be rated for 12v-18v.
What I really need is an adjustable voltage and adjustable constant current circuit with a display any thoughts gang I'm going to be using it for a bench supply for a lot of Differant things thus the reason to make both adjustable even at full output
You are going to need something like is linked below along with these PSU's.

great information thank you. Is there any risk in floating both power supplies in a 24v configuration?
Yeah baby! Harbor Freight meters!!!
I got probably 20 of those meters. LOL! Used to go there a lot and that was the only free coupon I was interested in. I'd give one to my wife and kids so sometimes we'd leave with 3 or 4 meters. I am not a hoarder...no, I refuse to believe it.

Should i float the pcb from the grounf if I only be using one power supply?
Nope, you can run it as is if you are only running one of them. www.Rc-Help.com
@@RcHelpDotCom Thank you for the info! and happily to have a power supply for my flyback driver or induction heater.
Nice video, would it be ok on the 1 psu put instead a foam piece, a thicker nylon washer under the board and then a nylon screw in? :-)
Thank you for your response, i don't think nylon is conductive :-)
i have a question, what if i want to wire the power supplies in parralell instead of 575 ones 1200w ones , 2 of them. do i still have to float it in order for it to be in parralel??
has anyone attempted to communicate with the ps with the PMBus protocol?
Hi, I am converting a Dell C8763 PSU, any ideas about the circuit diagrams and arrangements for the switching pins ?
I did a search and I'm not finding any information on a pinout of that PSU.
@@RcHelpDotCom Is there any way to ask the manufacturer(or any one els) for the circuit diagram ?
You can try to email Dell, but I wouldn't hold my breath.
@@RcHelpDotCom Ha Ha Ha , I agree , Please let me know if you find anything.
nice vid.do you have any compaq power supplies? i have one that came out of a server .the connects are basicly the same except i have more'.any suggestions?
thank you.
hi great video. Just wondering if you know of good inexpensive 1000watt 24 volt compact power supply for an onboard escooter build?
thanks
thank you
so even if i use a 12 volt 1000watt power supply the charger wont be able to charge at 1000 watts?
sorry I meant 1000w not 100.
Ebay
What is the danger if you float the DC ground in both?
hey rchelpdotcom i am doing a other project witch makes me use 2 power supply's in parallel do i need to remove the grounds ?
You shouldn't need to float a ground if you are just wiring them in parallel. Stranger things have happened though so do this at your own risk, but with no positive going into a negative terminal, I think it should be fine.
Where did you get the 2 power supplies?
Ebay, amazon. Ask IT people at your work, may be they trash some old servers. Also quite powerful power supplies could be salvaged from network switch.

Can any pair of identical server power supplies be used?
I think Yes, but not 100% sure on that. If one goes bad and you have them in series and they are not of the "floating DC ground" type, then you will get an outer case with full mains voltage going through it. I would definitely have someone that knows these things look them over to make sure they are safe.
What does the bullet look like on the charger side? It is covered up
+RcHelpDotCom at 11:29 the black and red wires how are the soldered to the prongs? Doni solder both onto a 4mm female plug?

If you are only using a single power supply do you need to float it?
Thanks for the quick reply. That sure makes my life easier.
if i only plan to use 1 server power supply do i still need to hot glue the board and remove those 2 wires ???? @4:40
Wow thanks for the rapid respone, i hope this also helps someone else. Thanks RC Help
