Hi I'm down in the dumpster room and yes I have my real camera with me because I found these on the way down before and I posted them on Twitter asking people yay or nay, should I bother getting them These are our Dell dimension C5 2 ones. They're an AMD Athlon x2 dual-core thing I think it's a 4400 a pass mark of like 15 1600 or something. It's like me like this: there's nothing really special about these at all. They do actually have some Windows Xp stickers on them, but like there's no USB 3 on these things.

like pretty much my requirement these days. I Hate to say it, but my requirement for take your stuff pcs from the doctor's dumpster is it's got to be pretty modern. It's got to have like USB 3 at least and a reasonably modern processor, but this is like eight years old at least I think and it doesn't seem to be really a huge benefit to taking this. Please let me know if I'm wrong, but we have a look in there, but there's no RAM the CD drive is just flapping around in the breeze there.

and yeah, you know it's got some PCI Express slots and stuff like that. but like the little power supplies are nice. might sort of nab the power supplies out of them because they can always out come in here, especially those little compact one. So I think they're probably worth worth getting I'm sorry, no it's not.

It's a right-angle one. I thought it was just that sort is there. but it's actually it's actually right angle. but yeah, power supplies are always handy.

so there's two of those. so I don't think I'll NAB those I've already got enough of these compact form factor pcs. There's a whole bunch of other crap in here. look at this and there's also two Dell monitors which were tossed out at the same time as well.

But I've already got a metric buttload of monitors. and pretty much my requirement for taking monitor this these days is that it's got to have a DVI input. This one's only got a D 15 your old VGA input. So yeah, I don't really want those.

There's two of those. it's another one up there. so they presumably came with these machines. But what I might take is this rackmount.

UPS I Don't know what brand it is I haven't touched it or taking it out yet, but let's take this back to the lab and see what's what. The batteries almost certainly dead in it. but we'll have a look back to the lab and here it is. These things weigh a ton.

They're really super heavy. they're all batteries of course. and there's your mains import. Got a USB interface is that it looks like some sort of circuit breaker serial interface and what's that? I guess some Ethernet monitoring thing and for mains outlets as well and let's have a look.

it's a HP now I don't know if he's pre actually design and manufacture this themselves or whether or not it's some some other Oh am I I presume HP do design a manufacturer Anyway, it's the Are 1500 G3 for those playing along at home. 1500 watts by the looks of it. Yeah, if you've been under what's the output capable of 1500 V a thousand watts output capability. Watts is different.

The VA won't go into that and it's yeah. it's a pretty decent unit I am seem to believe and it's a pretty decent unit. I'm not led to believe it even comes with a quarter of a million dollars Yankee bucks in load insurance. So if something goes wrong with this and it blows up quarter of a million bucks worth of you know, server computers or whatever, then you can sue the arse out of page, put your HP's insurance company anyway and get your money back.

It's supposed to have hot swappable battery size. Presume that they slide out the front. They probably like huge big ones like long ones like this. I Don't know.

it's flipping around. looks like there's only one. Well, there's only one. Bay Anyway, open, close, big-ass connector on there.

Not sure what that connector is and just I'll load one load - it's got a cut. It can do two different loads. Can it okay spread across the four outputs I guess Anyway, let's rip the battery up. How it works is you take out the screw and looks like you slide all right.

Slide this across. how to open close a part of the there we go. There we go and it's got some pull tabs. Oh yeah, it's got a whole bunch of little E's Wow Bobby Dazzler made in Taiwan and I don't see s3 I don't know.

Battery pack assembly replaced with spares got a date code so 36 volts total 9 amp power, 6 volts number about re six pack assembly. not sure if there's a sure if there's a date code stickers on the back. they're all high pot tested power test at all. That's how I've got a bold yet is that a protection he doodad mmm-hmm Anyway, let's measure the pack voltage 0.6 volts.

Yeah okay, it's pretty cactus CSB Battery Company but it's actually Taiwan Josue better. That's not like Yazoo Who makes the transceivers is it? anyway? I'm Dennis who is it? Is it? CSB Is that Taiwan Yazoo or is it Penniston battery stretch I'm not sure it's made by anyone of all three. HP dot bi my Brazilian viewers. There are rules as all the Warrior, We can just get the individual batteries out, so if one or all of them fail, you can simply get replacement ones.

But you know they'd cost a fair bit to get decent quality ones to replace this. So you know I think when you sell something like this, the value of it's actually probably in the batteries. All right with the lid on this baby, she's weighs a heck of a lot less without the batteries. Let me tell you, this lid should lift straight off and warranty void sticker is peeling off, but it's not actually off.

There we go, it's gone Ski now. come on. Firmware Version 1.0 for for those playing along at home pool Dave Idiot. All right.

Oh, we're in. Wow, that is a one big-ass transformer. Check that out. Wow it It looks odd ball.

like it's like wedge-shaped That is why. I Probably guess we've got the windings coming in from these end so there's some extra bulk up there. I Guess yeah. I Think that's what it is.

Big ass Earth terminal down there and all of the outputs are wide in parallel, so so much for it. Like isn't it supposed to be jeweled? Didn't we have jewel Zone on the front anyway? Maybe that's an additional model or something like that. So just a tiny board down there. They've got some got some snot on there holding the connectors down, but it's all nicely.

They've got heat shrink over all of the cables over all the ribbon cables running through, so that's very nice. Nice attention to detail. It's all cable tied down which is excellent. Oh Big ass relays on there.

This would make for a like, you know, you wouldn't toss this out there's you know, lots of stuff you could sell out of this baby. No, this thing here is it's like some sort of like expansion port, but it's like it's a logic thing that's got nothing to do with the power or anything like that. It's got the two ribbon cables going over to. there's nothing in there.

So I've got a finger? the port. Ah, isn't that board? Beautiful! I've got a whole bunch of nice relays out of there. you can really salvage those. They're handy.

Big-ass common mode choke down here at Nice. What I notice is if you have a look down here I've got a bigger small. There it is and inside there you can see they've got a little thermal fuse attached to that as well. They're using the heat shrink to like better thermally.

couple those so they're not. just start so the thermal fuses not flapping around in the breeze. so dual protection there to, uh, stop the mob from, you know, exploding. They've got another one down here as well doing exactly the same thing and that looks very nice.

I Don't see any any damage on this thing at all. Nothing looks blowing or anything like that. So I wanted to sort of check that before I powered it up and everything looks hunky-dory Look at that output inductor that is enormous. Wow and there's a lot of power on those heat sinks.

What's a parallelism? A couple of 40 amp fuses down in there. They got to 40 amp fuses since 500. VA This thing's supposed to be what 1500 VA Is it the only major cap inside this thing? BC So that's decent quality. And of course, because you don't need this, don't need any large capacitance inside this thing because it's just charging and discharging a battery basically.

So yep, and of course you've got a sinusoidal A I'm sure this will be like a a proper pure sinusoid tsiyon. Miller sinusoidal output I'm sure. Now that square rubbish. And for those playing along at home, that is how you mount a 7805 regulator.

None of this flapping around in the breeze. Rubbish. It's on its own little heat sink there, quite substantial size, one end and that one's bolted or soldered down to the PCB. Then you to-220 package just and bolt it into there with a shake proof washer.

Brilliant on-board fuse down in there that's not easily replaceable to ant 250 volts, but it looks intact so everything's looking pretty good on this thing, so be pretty confident to power it up. You've just. the batteries have died on it. There's only one little teeny tot fan down in there.

This thing is supposed to be super duper Blackmagic efficient, so put some specs up if I can. And yeah, so it doesn't need much cooling at all. Oh, there's the backside of the heatsink. Ergo, it's got it.

Ah, look at that. Is that like a welded tab? sold? a tab on the back of that? Oh, that's just so nice. So have a look at the down in there. I RF something he interact International rectifier Nice.

Okay, first of all, power that would. no battery connected. Maybe it doesn't need a battery? Oh I do wonder why they actually bolted they I use it a termination for the negative connection over here. but the positive one.

this is solar directly down to the board down there. Why would you differentiate that? Check this out. I Was just gonna say this is a big-ass the mister here and look at that oopsie, she's broken. That's interesting.

Is that why it doesn't work like that would be I presume that would have been like an output thermistor there from the other one here seems to be intact so I don't know it is flapping around in the breeze in there. They didn't bother to snot it down. anything like that, which we're done with. you know, a few other components is another move in there and various other whatnots.

but yeah, um, she's come out again. No, had nothing to do with it. It's not hugely surprising given that it's like in the output side of the battery or the input charging side or whatever. Mm-hmm All right.

so let's plug the dead ass battery back in. but at least you know it'll have all sorts of protections and stuff like that. So if it's like, like it shouldn't try and like if it's dead, it shouldn't try and charge it, then all that sort of jazz. So anyway, no, this puppy's dead.

No wonder they tossed it. Now it's not the input fuse which is a thermal fuse over here. so it's it's not that I've measured that. that's hunky-dory And of course they measure the mains input and you get like a Meg or something like that.

So we've got the input over here. It's not going to be the mobs I Check the fuses for the mobs. they haven't activated so there's been no like, you know, thermal, cut out the thermal overload or whatever. And of course, if you measure the input there you go, you know you've got a few.

Meg's something like that. so it's all connected like on the other side and everything. So it's something like you know, downstream and you measure that at the mains input of course. So there's something like downstream of that.

you know they've got the relay switching here to switch like the mains directly from the input straight through to the output over here. So when it's not in battery operation and then of course they'd have with some other big-ass relays in here to then switch the output of the inverter coming from here over and the mains. But yeah, I'm sorry, but this is not going to be a big troubleshooting video. I Found one issue they are by the way I soldered that back in and yep, so there you go for those curious to know what those are, the misters down there are like no, you know in the order of our 1.9 Sure, that'll be the same for both of them.

Well, the other ones 2.4 in measuring the output of that 5 volt regulator in there zippity-doo-dah So yep, no, there's no logic, which isn't surprising because then you'd expect that leads to power up and it to go beep beep and whatnot just to show you that we are getting well in this case, closer to 250 volts here in the lab. It's pretty much on the high side, even though we're supposed to have 230 volts in nominal here in Australia now it was 240 the load at 2:30 But anyway, lots of errors. But yeah, I'm close to 250 there and we are getting that across that input choke down there. So it is actually getting onto the board and the primary of this transformer here which looks like it's here I'm getting 9.2 ohms so that's intact.

It's not like it's blowing and of course there's no visual signs, but you know there could have been like an internal thermal fuse or something. but the primer is there. Okay, now this is interesting. It's not your traditional transformer.

We've got basically three wires coming in a well. 3y is here going off to our board where we've got I measured across. Here we've got 9, 9 and 1/2 ohms or there abouts and there's one coming back. so they those two go into the this side here.

let's just call that the primary side even though it's not really going to be a secondary and then got some additional one to additional windings that go over to this side and then one wire that comes back out to here and that's it. So there's about 9 ohms across there and about point 3 ohms from there over to this other wire here. So it's not isolated in any way. So it seems like that is an auto transformer there, which is a non isolated, common input and output transformer rather than your traditional, you know, isolated primary and secondary wires.

So yeah, although transformer, but once again, that seems intact. So yeah, it's got to be something on the board I think so there really is nothing obvious there. and yes, that I did actually measure, not just visually inspected that fuse on the other side and that's fine. So yeah, we're getting 240 volts onto the board, but nothing else.

So where's Wally Where's the problem? Sorry, but this is not going to be a troubleshooting video. so I'm not gonna do. Why go through the rest of this because I don't have the time to do it right now. So this is just a dumpster, dive and teardown video, but there's no other signs of visual issues.

I Found that just by wiggling that around. That was almost. That was like not visually, you know I didn't see that visually, I was just like giving it a little wiggle. wiggle wiggle yeah and found that thermistor broken.

But yeah, everything else looks visually okay, so no problems whatsoever. I've measured a few of our misters in there you know that one down there and other stuff I measured those and everything's hunky-dory So yeah, not sure what the deal is, but wouldn't be a bad troubleshooting one. this one. maybe for another day.

Catch you next time.
