I don't understand the argument. If your gonna spend thousands on an amplifier then why not spend an extra 40 bucks on more power supplies? I mean, seriously? Slap 10 of these in parallel and go on about your business. If that's not enough, buy 10 more. You've already spent thousands on the box your expecting these power supplies to run. Why not spend a few hundred more and feed the box with the volts and amps it requires. Reminds me of people that spend hundreds on a dog but won't spend the money to feed it. Long story short, quit being an a$$ hole.
Server hardware dude. It's made to be 99.999whatever reliable under abusive conditions. A server shutting down because the processors are causing spikes on the supplies causing downtime is very bad. Also letting the smoke out is bad in a datacenter is a bad thing but fire setting off the suppression system is a disaster. They don't want that on them so they overengineer the hell out of them to not fail or if they do to do so in a safe way.
If it hadn't been for you, letting us in on these power supplies,we would still be in the dark ages,as far as power supplies go,I've converted over 30 of these and the 15v is the best I never have any trouble,God bless you BBI.
Most dangerous this with this supply is the center heatsink is hot with line voltage. So if you are modding these its best to mod it on 120v before hooking up to 240v. That center heat sink will tickle if your pinky touches it while trying to turn that little pot! 😂
The UL rating? Really? Has there ever been a single solitary 11M amp that was ever UL certified where the amp wasn't re-purposed from something amateur/commercial? ED:Looking at your results, the reason the voltage probably drops but the current remains the same is there's likely a current sense as well as a voltage sense within the PSU. Look for a high wattage, low resistance resistor. That may be a piece of heavy gauge wire even. I actually made an arc welder when I was a kid by cutting the secondaries off MOTs and re-wound with #6. Ran really nice with 3/32 rod. Made my neighbors lights blink! Wish I still had it. Think I got up to 8 transformers with the secondaries hooked in series. If you use likenesses of REAL WORLD COMPONENTS Ohm's Law accounts for that. As an example, if you have a signal generator with a 50 ohm impedance there should be a 50 ohm resistor in series representing that impedance or it's assumed and not drawn. In a lot of cases that's neglected though, because the difference is negligible. The "black box" nature of these supplies makes people kind of neglect that, whereas they may not when looking at a transformer based linear PSU. It's also worth noting that these PSUs are likely not a true interpretation of Ohm's Law in the sense that you'd have with a linear PSU. A linear PSU's power characteristics aren't really changeable input wise e.g. they're not "smart." This sort of PSU will vary the duty cycle depending on the load and that's a big piece of how they do regulation. I've been slacking, but I'm fairly convinced that making an analogous power supply (or supplies) for steel tubes is one of the final frontiers of big amps. I think that the massive iron PSUs are probably far more obsolete than the steel tubes themselves are, although they are admittedly effective. I have a pack of dozens of 480 ohm resistors to make a multi-KW HV load bank from when I get around to building something worth testing. I've been experimenting with the microwave oven switchers at a point. Interesting but really dirty. Got 2 dead ones from a local shop, both were fixed with a $2.50ish transistor. It's worth noting that server people are VERY risk adverse and in turn the guys who designed these supplies almost certainly are. You can go into a data center and some servers will do nothing but get held against the rev limiter for literally years straight. These PSUs are designed with that in mind, which leads to the head room.
@@BoxBuilderIdahoI don't get your point man. Anyone into this stuff knows everything you said just to get a ticket to the show. I'm not trolling man, the video is great for people not familiar with smps topologies with advanced pfc. Dgw you are not though sir. You just need to read some datasheets and figure out the pid feedback loop to safely modify it. A labeled schematic reverse engineer would've made this alot more interesting. Server psus have been a known quantity since Al Gore invented the internets and us plebs learned to read datasheets and do some math and peep some waves. 34 minutes in and crowbar and schmoo are about as technical as this got. I'm out. You're quite condescending, I've seen no reason for it. If I'm mistaken then I apologize but you're coming off as a know it all. Ul certified as well means it has been pushed to failure, if that was in a server farm then insurance I'd say would demand it and when it's amortization period is over the bean counters approve a new one. I couldn't finish, this video was 55 mins too long and I'm being generous.
I did the 15.2v mod to mine, and have run it VERY hard on 120v. I have an SGC SG-500 amp, and run fT8 through it. That's very close to 50% duty cycle, on a 15amp 120v circuit. The fan makes a lot of noise, and I experimented with putting a quieter fan in, but it continues making power. I just slap a heatsink on top of the case, and that keeps the fan quiet longer. Thanks BBI!
I have one of these PS and have modded it to get 13.9v output. I connected 2 x 100w radios, 3 x 50w radios, a 250w linear amp and a 580w linear amp, I also added all my meters that have 12v required for lights and activation, etc. And it's also running ALL my LED lighting for my desk and radio shack. One supply for all of it. IF I run the big amp, at full output, the current drops to 13.2v, if I simply have everything turned ON, but do not load anything up, the supply cooling fan doesn't even turn on and it will sit forever at 13.9v. I have NEVER required more than about 60 amps for anything I have done, and I doubt I ever will require 100 amps of current. I have watched many video's on this channel showing HUGE power amps being driven by these when ganged into single power supply, and in THIS video alone , the numbers don't lie. 133 amps output, and constant 100 amps at 14.9v says to me everything I'm seeing indicates using these as power supplies is not only safe, but economical if your require HUGE amps for your 10KW linear.... I am NOT a power supply or electrical genius by any means, but it's HARD TO ARGUE with the video evidence shown right here by someone the KNOWS what he's talking about.....
The Ohms law conversation…. You right guys wanna cherry pick which formula they take off the pie wheel chart. When I first was around Variable Frequency Drives ( VFDs) I would watch motors start rump up and run at anywhere from 30 hertz to 70 hertz on 60 hz motors that where anywhere from 1 hp to 350hp 480vac. And there was time I thought they was breaking ohms law too. The I found out about SCRs or silicon controlled Rectifiers that were feed with AC and had AC on the load but DC in that circuit within that drive. Hence the SCRs . I’m guessing there is way above 60hz inside the circuits before being finally rectified to 15vdc
Looks like you've proven for a second time that these switchers are far better than supplies like my old astron 70 amp that pretty much gave up at 90 amp draw.
Ok, that was probably the most impressive electronic test ever! The multiple redundant protection systems make it a tank. Under normal use they would last forever. Wow what a product, well done HP! Thanks for the video/test BBI. 🎙⚡️👋🏼
Awesome testing. We use many Schneider power supplies and they won't let you grenade them. They have put in so much safety. In the end you will just blow a fuse that's it. Put new fuse and its good to go. But we are only talking about 5 amps at 24 volts but they go up to 600v ac/dc. Just keep the fan clean and no food products dust oil and dirt and they work
I've been running 2 of them separately @ 14.5 v ever since your video on them dropped. Not one problem to speak of except i was driving one hard and the fan kicked into high speed. I unkeyed and let it rest till fan ramped down. Its been running fine ever since. Thanks Luke.
I tested one on 110v modded to 15.3v and achieved 93 amps at 12.2v and 94 amps at crowbar. 89 amps maintained 14.4v. I ran for about 20 minutes. I didnt have a flir so I tested with a lazer thermometer and the hottest mine got was 121 degrees before the fan went into apocalypse mode. I love these things. I have 3 tied together at 15.3v on a single 15amp dedicated 110 outlet. I was able to pull 286ish amps before the circuit breaker tripped for the wall outlet. I feel it would have gone farther had it been a 20 amp breaker. Only thing was my voltage dropped from 15.3 to 13.4. I had a cheap, 500amp harbor freight carbon pile for my tests. I am kicking myself for not doing a video now.
I use to work on backup 2 meg generators at server centers. Got to go in the big server rooms. What a site to see. I don’t know what the temperature was but was cold ….
Hello Fellow Amphaulics, Friends, And Supporters Of The World Famous BBI AMPS: Thank you for this switching power supply video. Luke are these the switchers you plan on using in our project or are you going to use the bigger ones ??? Thank you again for this video. TMP, Unit 22 from N.J.

I took two of these supplies and slaved them together. I did the mods BBi talks about in a previous video. I am running the supply at 14.5 volts so that I can run all my DC equipment in the shack including a 4 pill running 450w at 40-50% duty cycle on 10 meters FT8. I was able to retire all my small supplies and run just this one unit. DC voltage remains stiff at above 14 volts at my full load conditions. I did put the two slaved supplies in a fused electrical project box and I have a 120mm fan feeding the box with fresh air and the supplies are orientated so the supplies exhaust out the back of the project box. The main takeaway is these supplies are as safe as anything, if not more so, then anything on the market coming from China today. Experimentation is the corner stone for Ham and CB radio operators. Setup right these supplies will outlive you :) 73 Joe
