 Hey there YouTube. So I set up a transformer with two outputs, two secondaries, and I've given them their own smoothing capacitors, and they've both got their own little very basic 317 regulators. Now this board, even though these negative positive rails go the way through, I'm actually connected to these, so they're independently powered. The ground comes in here, and the output comes in here. We don't actually go into these dual-alson. These are two separate power supplies. And the interesting thing about that is, in order for now, in order for me now, if I want a positive-negative rail, all I have to do is connect the, well I can connect this output, basically I could put that there, and use this, the positive output, put it there, and use this negative and connect it in here, so they're connected together. And what we'd have then is a center point, like a zero point, a negative side, for an output here. So you've got two independent outputs, and then if you hook the positive and negative together, you've then got like a center tap on these two outputs, which will give you a positive and negative rail. And I'll show you, if I put this on, this is, I'm just going to measure them both separately at the minute. I'll connect up there, connect up here. Zero volts, and if I give some power here, as you can see a little bit, we're set up with smoothing pastures, they've both got separate bridge rectifiers, and then we've just got a 240 volt input here in rush filter, limiter, sorry, resistor. So connect that side, 1.2 round volts, pretty much turn the way down, I'm going to take that up there, come over to this other side, and again, make it the same voltage, pretty much the same voltage there. And if I just use this pot, turn it up, as you can see, all the way to 29.3 volts, with no load, of course, with no load. And that's going to be the same one. Let me just disconnect that, so we can start to see that from down, but just while that's doing that, I can put this on to this side, and there, of course, it says 1.3 volts, and we can go up on there as well. It won't be as high now because the capacitor is discharging. Turn up that value. And of course, the way we want to see it is, if I take that out of there, and I get a little blue wire, negative in there, I'm going to join that across here. I'm just going to take another wire out here. So now we've got, this will be a negative, and this will be the positive side. But first of all, let's just connect up, and then I'm going to put a second, let's just connect up both sides, so we'll have a positive on there, and a negative on the negative side of this supply this time. Okay, so that's still in the 200 volt range. It's down this time, and which side's all the way up. Okay, so this is with them both all the way down, so it's 2.6 volts. That's both 1.3 volts added together, of course. If I turn this side up, hopefully you can see that. If I turn this side up as well, there you go. Now we've got 56 volts there. And at 56 volts, I did think about it. I thought, well, you know, will that have an effect because of these regulators? But I put 317HVs in these, which means I've actually got the input-output difference on these. It goes up to 60 volts. So we're good. Now if I put this on here, which I've recorded that, and get this one to here, that's the positive. That's the positive channel. If I come across with this over here, and go to there, we've got the negative. And the other reason that these are different is because I've just not set them both exactly the same. So you can have a positive and negative supply. I'll probably take that off there on this side. I'm just curious now as to 15 volts. Because that's going to the positive side of it, isn't it? There you go. Well, I wondered if it could be done. You know, I just wondered if I had two of these and I could put them together. And of course, you know, I suppose, really thinking about it, if I got two separately insulated power supplies, two batteries, let's say, I could do that. Two normal power supplies, you could do it. So there's nothing special and nothing new, you know. That's what I thought about. I just wondered what it effects would be. But I'll tell you what, I did find out experiments and I had these two N3055 some past transistors, one on each channel. And I decided, because I was using this load, first of all, trying to see, you know, how much ripple it was and using these. Using this like with these one on each. How do you do anything? Pretty good. And then I tried putting this bold one, this 60 watt car lamp. Well, all that happened was it lit up really brightly, really quickly. This transformer, because it's got 3.3 amps per channel. Yeah, per second, per winding. At 24 volts. But when you put them together, you don't get like 6 amps in series, do you? And basically what I did was because this would draw like 5.5 amps when it first kicks in if you put it straight onto like 13 volts and then it would settle down to about 4.5 amps. And all that happened was this made a lot of noise. I wasn't happy at all. It got very bright and pop. And it just killed these off straight away. Killed them. And the regulators themselves, they're fine. All that so I'd say fine. It was just the bit in between, it didn't really like it. So, yeah. Although it was quite a good experiment. But now I've got to get it off my bench because I think I figured out what's wrong with my Hobson H501 and I'm going to take it apart and find out. So, cheers for watching guys. I know it's nothing new or anything like that. I'm not going to bring anything new to the world, but it's going to be pretty good because then if you did have a transformer and you wanted to make a positive negative power supply and you had to transform it to outputs you could actually have two independent supplies and then when you wanted them I'll come up so you've got that dual row and when you don't you still can independently use two different supplies that complete floating away from each other. The only thing that connects them is the flux and the light you're going on in there. See you soon, bye.
