 Okay guys, I thought I'd just show you a few things about this, this is my Jordna, it's a 600 watt boost converter, it claims to work from 10 volts to 10 volts to 60 volt input and has I think it's 12 volt out to 80 volt output. This is fully adjustable voltage and adjustable current. The difference between this one and all the other ones like this, maybe a few others would be the same as this one but on my one I have the customization of the current adjust, it doesn't do anything. Okay it does a very slight something and we're going to see that in this little demonstration. So yeah so what we've got is I'm going to have this connected up to the multimeter just by these clips here which are attached, we're attached, it's attached again to that and I'm going to use this as my load. It's a heating element from a fan fire convector heater now, just a you know one of those little fan things with a heater in it that blows the air. And what we've got here is we've got this one is 52.84 ohms, this one is 51.07, this is according to my meter here. And the combination of those two using the probe here and a probe here is 104 ohms and these two together using that as the other probe is 25.98 ohms, so 25 ohms. So we can expect at different voltages of course then different currents to be drawn through this which means I get the ability to adjust and see if this is just as it is working. So I'm just going to put a second that's going to get a place but there's a couple of things I want to show you already and the reason why I'm going to show you this like this is hopefully this is what's left inside this circuit. Presumably here because this one's actually disconnected from pretty supposed people. I'm going to show this now this is 10 volts and the plane on this is at 10 volts. It's probably going to do it now just to put it on. It doesn't. Using this setup with that reading it doesn't. I can't say that's exactly 10 volts that's what I'm being displayed there but if I just turn this up I point one to there. Ah okay I can't exactly say that's true. Let's turn that back down to the 10. Now there's some juice in the caps. There we go and what I noticed was at this setting of this 10 volts on this power supply when there's some juice in the cap still you can chuck it back in and it kicks in. Look at that 13 volts. So it's it's working but when there's no juice in the caps and you put it back in it doesn't work but if you were to go up just point one of a volt on here at 100 millivolt on here that's enough for it to kick in. I'm going to show that now. I'll fast forward it through this bit. This should be near enough ready to move this now so 10.1 on there so it's at 10 volts. Let's just put it in now. There we go. So I suppose you could say 10 volts it does work because it's pretty close to the 10. We better want the display on this is reading probably or not. So interesting no load let's see what it goes up to. If we try and turn the adjust for the voltage all the way up and what will happen is when it gets past what it can actually boost convert it will drop back down to the output voltage. That's not bad from 10 volts. Now this has got no load on it remember so it's going to behave differently with the load on it. Quite a shock that's just going up but I've got a funny feeling that's just because it just changed resolution. So I don't know sort of speed up I expect to just go full open circuit. 80 volts it's claimed. Now on my pulse volume we're going to go down to 9.8 as you can see in the background 90. Watch my constant current. So I presume that's because I've got some sort of limit on there. Let's see if we get past that sort of 89 volts. There we go. That's because the limit was on 92.8 volts. You shouldn't know it's going higher on this because the caps are only rated for 100 volts. Give or take you know they're 20% or whatever. So there we go 1.1 ohms 1 amp 10 volts 96.96 volts. Enough to wake you up in the morning if you put your fingers on those contacts. Speed 3 winding this down. Okay let's just come down to around about 15 volts. So that's the lowest it can go. Well let's see what is the lowest it can go actually like that. That's that's the 10.10 pot and it's maximum down. So we have 96. something volts wasn't the maximum output that's involved in. Oh sorry about that. 7.1 volts in there. 90.6.7 I think it must have that number. And the minimum output is 10.9.6. Okay so let's put a load on it and see how it fairs our load. I'm going to turn this up so we can see it jump up to 13 volts and 13 and a half because we want to get it set pretty close to and remember what it is because um it's a little bit minor that's all we're done there. Oh whatever right 13.5 6 6 13.5 6 5 19.5 6 4 let it settle there we go. So at that voltage 13.5 6 4 let's connect and we know it should just like basically jump straight back to it. 13.6 4 13.5 6 4 13.5 6 4 okay fair enough that's what it goes without a load. Well let's just have a little uh do we do a let's say we put the 50 50m load on okay so that's going to be one of these the closest one to 50 was the one at the bottom fast forward through these bits and there's been things we can see how far now the 50m load it pulls it down as well if we're actually anything's going to work we're just going to use wires out the way else. I've kind of expected to be able to help this thing as well with uh uh with a 25 ohm load at 250 volts we're talking 10 amps early so we're not going to be pulling that through that um right okay so 10.1 volts and a 52 ohm load and I'm just going to turn my oh my turn on four blasts so there's no problem with that with more power spot 10 amps we're going to have in the right settings okay all right so we without the load when we kicked in we were 13.564 with the load kicked in we're 13.562 300 milliamps so that's just uh 13.464 forwarded by uh what do you say the load was? It's uh 51 oh so 51 oh so equals 0.265 and of course it's going to use um a bit for the actual converter itself because we're going up in in power and of course the more we turn the output voltage up leaving that low it is more currently it's going to want to use so let's do that and see what the cutout point in there will remember we had the top end the 97 volts 96.7 or so so that's what we have now okay 15 volts no problem 16 volts six and a half ohm we're still nice and there's around a 24 ohm load out of it okay this is still at 10 volts all right okay and let's say like 30 volts yeah i can hear my um transform inside there now i'm sure i just saw it drop a second ago so let's just put um we're going to turn it down so i don't hear my transformer don't look potty in there let's put this one to 30 volts i think that's the heating heating up so it's close to 30 volts as i can yeah not me and i'm supposed as this gets warm like 29 973 1.8 ohm so okay so i'm just going to literally just pull that out quick those counts this charge about 25 uh 50 ohm right on the having me to see now well it's got a load on it when we plug it in what it goes to and if it even works i'll flip in between 10 and 1 let's do it what do we have we have 29.973 29.97 let the side down 972 1.8 ohms i'm flicking between that um 10 and 10.1 okay let's see what we can do then on the maximum output if the power of my power spine sounds like it's gonna throw a fit but that looks like that's the maximum maybe i can get out of that if i just back that down again so okay let's put on to 45 then we're gonna root our power 4.4 ohms 24 volts 24.4 ohms is that getting that is yeah it's quite warm actually it's quite nice a nice winter's day okay let's just check that back in again oh look at that it wasn't really happy i think that was my power supply um but still 40 oh 45 i've got here and 44.97 that's uh that's pretty close let's turn this down because it's cooking that's really relieved let's try a different mode let's try the 25 ohm mode let's see what we get from that i'll pass forward to really expect the change in things around okay all right so now we've got a 25 ohm mode on there and i don't know what the water was 13.6 i'm close to that i didn't like it down i'm way still up it's got a high pitch noise in the air i don't know if it was this i think it's just a high pitch noise in my ear okay it was a 13.6 wasn't it if i remember i was looking back at the video so we got 700 milliamp drawn on it 25 ohm mode and now i'm gonna see if i can adjust the amps because it was one of the things about this that um doesn't work on here oh it seems to be working all right so that's all the way all the way this is a 10 turn path and i think it should be going down limiting the current something to everything as you can see i mean it is and that's fully limited so if i turn this up it's not actually called right it's actually on it now i'm gonna turn it to 20 volts okay close down it and i'm gonna turn up the turn up the current to see how far that's just going on but there's nothing absolutely nothing on this current i just so that most technique doesn't work you can hear me on the limits of the current i just so that doesn't work very well it's all good so now what i'm gonna do is i'm gonna turn this up i'm gonna go 20 volts on this and as i increase the voltage of course the load and the current goes down but that's to the maximum that i can give it 31.89 volts and of course this has now gone to the new um levies point it can go because it's a boost converter so it's minimum has to be just above my maximum but i would like that put in so let's turn this up i'm gonna remember this is now that i uh 25 aren't i uh 25 in like 25 yeah what you want to do that okay i can see i can see i think we're there okay let's go 70 and that's 0.9 that's near enough peak and that's the highest i've ever drawn anything from my um power supplies i'm a little bit scared there so i'm backing everything down it's a little tiny bit of uh it's probably just the dust doing warm and so there we go that's the uh that's the limit there so then as i turn this down of course that will go down as well blues with batteries you're using there we go so let's say between 12 5 and 12 5 and 12 4 so i'm trying to put it in the middle there um 25 ohm low 3 amps if you're using 30 volts i'm not sure what i can try and work out into about 25 ohm lows but it works and it's just real pity about the current adjust on this that's not really this isn't warm at all there's a little bit of warmth coming off that but yeah but it will certainly work at 12 volts and it certainly works at 10 volts as you can see and um the higher the voltage of course and the higher the end output um but if i remember rightly uh 10 volts it was good for whatever i think yeah 45 amps uh 45 volts it was good for wasn't it 4.4 amps and that was with a 10 volt input that's uh that's all right that's all right from there i think well it should be better if the uh current adjust worked but because that doesn't work it could mean that i end up getting that as a freebie anyway if you found that useful at all um use the thumbs up if you like uh i'll catch you again soon bye
