Video to hack dps-1200sb • let's volt Mod a Hp,dp... Video testing power supply's in amp • Ro#5 BBi Built Super 6... Here is the link to the seller on e-bay www.ebay.com/i...
These have been used in the RC world for a while. Big Lipo chargers like the iCharger 30 series and 40 series chargers need a big 24V power supply to operate at their maximum ratings so series connection two HP DPS's was found to be less than half the price of the power supplies the RC websites were selling (and they weren't putting out enough power to max out the biggest iChargers and other 30/40A Lipo chargers)
Can't learn much by skipping through a video. Personally I value the knowledge you share with us and waste your efforts by skipping through your videos.
Very much appreciate. Like all your videos, it's nice to see someone that makes things, not excuses about why they won't work. Excellent work. from a ham with no snaggle-toenails!
What an Great person doing a great work. I actually Bought 3 of these same models for an mod which only some chosen ones decided to do. I want to apply 240 Volt Dc from solar and use this to charge my 12v battery bank. Unfortunately this does not turn on 240 to 200 volt DC and It turned on instantly with 240volt Ac. I tried so much to mod it and read online articles so much but this model is not turning on high dc voltage. My other smaller switching power supplies of 5amps have no problem running on 240 to 200 volt dc but this model i want to run is not turning on. Please help me if you can in any way it will be much appreciated. I want to use this as an mppt from solar.
That was me that made the online statement on one of the FB groups but was careful not to mention you directly. i did not see any other videos beyond the one i saw where you were talking about these HP supplies and was really wanting to know how to correctly wire them up. Now that you have detailed the "how to" for these, I will relate that back to the FB group. Sorry if anything I said was taken out of context, I was simply trying to gather this ^^ information. Thanks for detailing everything.
Thank you 👍. I'm going to try one with my TS 480 HX Kenwood HF transceiver. Just about all of the switching power supply's I have tried are noisy on 40 and 80 meters, kinda annoying. This is a whole lot more cost effective than a 70 amp astron transformer power supply. Not to mention weight. Thanks and 73 GOD bless Earnest K5EWM 👍.
What type of 12 volts 300 ampere power supply is best between :- SMPS, EI Transformer & Torodial Transformers for playing one 12 inch, 2,000 watts rms sub-woofer through one 3,500 watts rms mono car amplifier at home ? Plz suggest
BBI You were sounding beautiful over here in new york 2 minutes ago, I was trying to call you on the radio but my mudduck 5 pill station just doesnt have it over those other boys. Thanks for all your help over the years brother! godbless and keep keyin down!
I'm not a box builder or run any stuff anymore but I'm still thinking of picking a few of these up. I mean 100amps for 20-ish bucks is ridiculous. I payed like 300 for 70 amps when I bought an Astron back in the day. How could anyone pass on this? lol
I think over the next 3 months. I’m going to reverse engineer that, and play with the schematics a little bit. 😈 just as a side project to screw around a little lol.
.thank you for this helpfull info. Im from Holland, soo my question about this amazing model is, do this only 110 Volt, or is it switchable to 220 Volt ? And how much do i need to start my 1000 Watt Airconditioner..thank in advance..have a good day~♧~
3:57 There are many, many people out there (actually an incredible huge amount) that doesn't want to do a god dam shit by them self but want everyone else do it for them for free so I was not chocked at all. "Why should I look at the video at all when I can just ask him, you do the work for me! I don't give a shit just do it because I tell you to!" That is the average Joe on RU-vid.
Hello sir , great info , I build 18650 charging boards and I’ve been trying to find a mod just like this … for ever 4 packs of 4 batteries I need to add a PS thank you 🙏 sir
I ordered a bunch of these puppies! So freaking happy to be able to build affordable supplies for my guys!! People are getting tired of me telling them $600 for a 200amp power supply, Now I can make the box HALF of the size and charge them HALF as much!!
@@joshchilders-fy1pk wtf are you babbling on about? Because I don’t post videos of my builds and jobs means I don’t know nothing about supplies? Wtf lol
@@Tomahawk-415 ya I forgot about the crowbar, I’m thinking a duel faker 4 position switch with the required resistors for both the vdc and crowbar circuit. Example position 1 would be 12vdc position 2, 13.8 vdc and so on. Would just take some fooling around with resistors.
hi bbibeauteful vide server suply have a lot o futurs votage control fan speed curent sering up to 4 units i think stability no noiz on cables they also hav a pin power ok i usualy put a led ther indikates separatly 13.8 is working i ben using a dps 800gb model a small coper bord wit extra caps and adorson powe poles istant 72 amps at 13.8v
Great videos. Clicked on your link for the EBAY seller and seems link is no good. Any chance of posting the sellers store link? Very interested in getting started. Thanks. EDIT: Found him but no units listed. Is there a difference between the units with the blue plug receptacle and the black one other than color? A few on line have made reference to this although I see no difference. Thanks
Great video I have gotten other models before i seen your video they seem ok. I have not done any voltage increase mods yet just getting started. There fb 1A pd-19 same turn on way .I also got a Samsung power supply for 9.00 tried it same way just about to turn it on pin 1and5 have not seen any mods for them yet. We shall see it's on back burner I'm a hobbyist not nearly in you're field I am only as smart as you tube lol. I have been in dc fork lift repair before i retired have some experience. So in closing thanks for you're video's.
I have a delta dps-500gb h and I’ve been hunting for a while how to do this mod to it and I can find nothing🤦🏻♂️ any help would so greatly be appreciated. I am kinda out of options lol
Good Morning Fellow BBI FANS & FRIENDS: MR. LUKE I believe you have opened up a new world to those searching for a switching power supply alternative that delivers heavier current output with just a little love & affection. Thank you for another informative video, God Bless, TMP, Unit 22, from N.J.😊😊😊
These plus are completely idiot proof.. You can stuck a screwdriver in them any where a ytime and after the "Splat-bang" its a really simple matter to scrap it for spares and buy another. When that goes the same way ? - why you have all those spares just connect pin 1 to pin 4 ffksk ! What could be simpler ?😂
hello Mr bbi. I have one question . I have a 2x8 . why is my swr high on output. swr changes with power output the lower the dead key the high the swr . and when I modulate it swings backwards? I don't think it has anything to do with my coax ro antenna . because when I run my 2x4 the swr is fine . can I get your opinion on this matter please. thank you . Mr bbi.
Heather work exactly the same the difference is the mod on the inside of the power supply.. it requires a different set of resistors in a different set of locations. All that information is out there you just have to go find it
Has me thinking better buy some of these before "_____" starts making fake ones or they start putting new labels on junk ones. side note: 1875 sold on his page.
There are actually many more server supplies from HP and Dell that can be modded in a similar way with slightly different pinouts, and layouts. It just so happens that he has one of the only videos that go into enough detail of this particular part number. Doubt China will notice. Dell makes a 3000w unit that is only about 1.5x's this size. HP makes a 1500w unit with yellow label the SAME size.
@Mr BBI actually they are almost at 100%. The idle voltage is 15.9v on your supply, and the max is 16v on Caps. Easy math.., dunno where you got the 95.5% because that's wrong, it's actually 99.9%, to be exact, not including inefficiencies. 15.9v X 99.99999% = 15.89999841v The usual tolerance is 10%, but remember these are used, and probably have a billion hours on em. Caps are cheap, I'd replace em with a higher voltage rating, especially pushing them to the voltage limit. It's not any different than rebuilding an engine and putting USED crank bearings back in. If 1 Cap shorts from running to hard ( and WE both know eventually they will), the entire supply goes dead. Food fer thought:)
@Mr BBI I am in the UK, different supplier but I found out the problem! My multimeter probe was faulty! So I have 15k on the variable and 51k on the chip and I am seeing 14.5vdc working perfectly!🤗 thanks for all your help on this project bro! All the videos and the chat in the group have been super helpful!🤗👍🏼 052 in Scotland waving a hand!👋🏴👍🏼
In most of these supplies the mains ground is connected to the output ground, so series connection requires modification. Also put a serious diode in parallel with each supply to prevent backfeeding power if one switches off.
Hey Mr BBI. Have you thought about drilling holes through the board where the positive and negative strips are. That would allow for 100% wire attachment for those that don’t have big high watt soldering irons. I’ve modified a couple different power supplies over the years. This by far seems to be the easiest. I ordered to and should be here this weekend. Thanks for the info. I love watching your videos
I've seen a couple people mount lugs of different kinds by drilling through the strips. I'm hesitant to try it but with the PSU's being so cheap I might give it a shot. Would make my 4mm binding post/banana jacks much more secure because currently I'm soldering them which is secure but takes a lot of solder and isn't the cleanest looking. Just gotta make sure you use high quality solder. I use MG Chemicals 63/37
I know! I'm just fucking with ya! I absolutely love your videos! I take electric stuff people toss in the trash and I have a ton of server PSUs! I'm currently going through them to see how many can do the same things! Love ya brother
Oh man. Luke my Brother, you're a technician if I'm one and I'm pretty sure I'm one. FWIW, over 60% of the guys who made the Apollo project a success didn't have "Degrees" A self made man is damn hard to stop!
I took a chance & ordered 6 of them. Gonna build a power supply and I wanna do a rack mount supply to slide in the rack I’m building that will hold 3 of my most frequently ran mobiles,Johnson 223 & Galaxy Meleka.
