My UPS is designed to run on 36v Dc input. Can i be able to use a single 12v battery for it to run? if not is there a way i can adjust the input power to 12V?

I am wanting to build an Uninterrupted power supply. I was planning to use relays to connect and disconnect and the mains and battery power. N/O for the mains and N/C for the DC voltage. I wasn't sure if the relays would switch fast enough for the CPU to remain on. I loaded 2 pictures. Has anybody ever built something like this?

Does anyone else seem to think that a lot of the entries here are not technically mash-ups. I entered one that, the more I think about, isn't really a mash-up. Sure I combined a couple of things to make something new, but unless you consider turning two decorative things into a third decorative thing a "mash-up", I'm not entirely sure it fits this contest. I'm working on something that I think will be more appropriate, but I'm curious what everyone else thinks.

Hi Guys, My first time to post a question here. I had purchase a UPS from a store. The UPS have 2 6 volts battery inside of it, the seller said that 1 of those battery isn't working anymore. My question is this, how do I replace or is it possible to replace it with 1 12 volts battery instead of having 2 6 volts battery to fit there. What will be the layout of the wirings if I have to do it on 1 12 volts battery. I tried making search of the actual item on the net but couldn't find it. Here's the pictures and the information of the UPS Information -------------------------------------------- 2009000002391 MODEL: ELITE 500 VOLTAGE: 220V / 60Hz MADE IN TAIWAN --------------------------------------------

With most UPS's there is electronic circuitry to reduce the home voltage to 12 or 24v to store in the battery, and then another circuit to raise the voltage back to the home voltage. I know there is always a loss when attributes of electricity are changed. This seems very wasteful to me. I want to build a UPS for my notebook computer, that I use as a home server. The power adapter for the notebook creates 19 volts but the notebook itself uses 12 - the other 7 is perhaps used to charge the battery while the computer is on. I would like to put together a UPS made of 12 volt Ni or LiFe packs - would most likely be 13 volts but I don't think that would be a problem to avoid the double switching of the power. Can anyone point me in the right direction?

Contrary to popular belief, I havent left instructables, and I havent died. I have however been working on bunches of projects (some of which you may remember from my "Things I'm Going to Post Soon" slideshow). Unfortunately, most projects, such as a crossbow, slide-action pistol, semi-auto sniper, etc., have miserably failed. And even worse, several projects (FAMAS, M6G, and the D.R.A.G.O.N) have been demolished for lack of pieces, and will need to be rebuilt. The first project to be posted will be my M6G Magnum (halo 1 pistol), which should be up by the end of the week, followed by my completely new Sniper, the KSR (at least until I find a better name), which I have made since, according to previous feedback, my R700 simply wasnt cutting the jib. It features an extremely comfortable handle, an upgraded trigger system, and better overall statistics (range and accuracy). After that is posted, I might be able to rebuild the FAMAS, or the DRAGON, but dont get your hopes up, they are hard to remake, so I'll probably just make a new gun, such as the Shipka SMG. Stats: M6G Magnum •Range: ~ 20-30 ft. •Accuracy: Consistent •Mag: Loads 9 pcs. KSR •Range: ~65-70 ft. (depending on bands) •Accuracy: Very Consistent •Mag: Single shot / rail system FAMAS •Range: ~30-40 ft. •Accuracy: Good consistency •Mag: Loads 12 pcs. D.R.A.G.O.N •Range: ~50-80 ft. (depending on ammo type) •Accuracy: Medium consistency •Mag: Single shot / dual rail system PS - Constructive critisism is welcome, but dont just say: "wow _____ gun sucks" The pictures are as follows: 1. M6G Magnum (w/ comparison) 2. KSR 3. FAMAS (w/ comparison) 4. D.R.A.G.O.N

Now I want to use both UPS together to charge a pair of car batteries (12V 35 Amp each). Is it possible to do so? Using two same model UPS on same battery? I know there is a possibility of power back flow / de-phrasing that may damage the UPS. Please suggest me if I need to use some kind of circuits to keep the two UPS separate. Thank You.

I hope this isn't a dumb question, but if I were to take an old UPS unit, remove the battery, wire a 12V lighter socket plug to the battery cables in the UPS, and plug it in to the car, would it convert the 12V DC to 120V AC while the car is running? And if it worked would it draw too much power or damage anything? I wouldn't use this to run anything with a motor, just a laptop charger and maybe a light. Thanks! :)

This might sound stupid, but I was watching some guys build batteries to Electrical Cars using Laptop batteries like Tesla does (18650 battery Cells) and I got thinking about creating an UPS for my PC. If Im not mistaken, most UPS convert AC to DC current and in a mains power loss they convert back DC to AC which is not very efficient I assume. So why not instead of going thru that process, why not power the PC components directly from the UPS in the event of a power loss or power supply failure?? My idea was to build a UPS that works completely on DC power, from its input to its output. So the PC power supply would charge it and the UPS would power the PC components in case of a power failure. I would be using this on a server so I dont need monitors or other stuff. All that would be require would be power regulators for 12V, 5V and 3.3V right? Wouldn't that be more efficient? (the battery would last longer due to less power loss on conversions I think) And wouldn't it be cheaper? Thanks, Ralms

Hey all I'm trying to hack together a few things to make a uninterrupted power supply unit. So far, I've got a 500W power inverter from 12V to 240V, and a car battery. Unfortunately, I also need a power supply capable of pumping enough amps into the inverter and battery to get the whole thing started. I've tried an old ATX power supply I had lying around (actually several :s and I figured if I can get at least a few amps out of it it'll power ONE computer at least) but as soon as the inverter is connected to the 12V line the power supply shuts down (even when it's not powering anything at all, just the inverter ATM). It's like some sort of safety mechanism, same thing happens if you short two wires across. I know there's nothing wrong with the inverter because I can plug it into a normal wall transformer (which fried as soon as I plugged something into it because the transformer only output 1A ), and it works fine powering a computer on the battery. Anyone know of a way of overriding this mechanism, or even better, a way of hacking together a cheap and nasty 240V -> 12V 50A power transformer? Maybe splicing two power supplies together, if it's possible? 'Shady

Nowadays many sites do this very horrible thing that is really annoying to the point I just want to throw my monitor out the window or beat the crap out of my monitor with my keyboard over and over. When you go to a site, like this one, you are reading the article, instructable, watching a video (or whatever), and few seconds to 2 mins later, the screen dims and a pop-up comes out saying "do you want to sign up?" Other sites might say "do you want to subscribe?" "Click "like" if you like this article" This is one of those things that's really fking annoying. If people want to sign up, they can click on it in the top right corner. The sheer amount of sites that do this, that forces you to read their pop-up, making you close it everytime. The only thing I am interested in is the instructable/artcle I was currently reading... This site would be decent if you removed it.

I've got loads of LEDs and resistors from eBay and using the resistors, only up to 4 LEDs in serial will light. I can't just use more resistors, as I broke open a mains lighting bulb that uses 20 LEDs to provide lighting. Looking at the printed circuit, they are all soldered in series. If I put + at one side of an LED and - at the other with these resistors I have, it lights, two three and 4 work, but on the 5th, it drops dim, after that it won't light at all. Do I need a different resistor, of is something else wrong. Could someone kindly tell my what resistor I need for 20 5mm White LEDs running off 18v (two 9V batteries), and 9v (one)? Thanks! Josh.

I recently acquired a very large 12V SLA battery and want to make a UPS for my computer. I think I have the basic idea, but I'm not entirely sure how I would go about this. I'm guessing I could use a relay to switch from the mains to battery, but then I would need a very large capacitor to run the equipment for a few milliseconds whilst it switches. I would need a separate transformer and regulator for the relay, and also an inverter for the battery, which I will probably buy as it looks like it would be too hard to make. Is this the right approach to it?

It would be great if you added runner-up prizes in some or all the contests of Pro Instructable Accounts. I am new and have not seen that, maybe you already have them sometimes, if so then please ignore this. But if not, it would be really great for those of us (me) that want one yet can't afford to spend the money on one. I know it isn't much to some of you folks, but it is a lot to others. The cost of the supplies of things we are going to make, which we will spend first anyway, it is already hard to afford. Adding the Pro account as a prize wouldn't cost Instructables much if anything and there is no shipping cost plus I think it would be appreciated by many. :}. Thanks, Conny

However I can not get it to trun on without being connected to AC. What do I do? I have tried two different UPSs. I am including ictures of my UPSs. The white one is APC 280VA model.

I've got access to 12 flexible Solar Panels - 320VDC each I live in the UK where mains voltage is 230VAC and also might buy an electric engine which would run at 48VDC. Would a UK voltage (230VAC) UPS be able to step down the 320VDC to either 230VAC or 48VDC for use on a boat? I'm thinking I could connect 12 panels in parallel and use either; Double-conversion UPS to deliver 48V by bypassing the conversion from the battery back to 230V or Line-interactive UPS to deliver 230V directly from the 320VDC. The question is would the UPS's surge protection be able to deal with the high voltages? (Keeping in mind the sun isn't real bright in the UK). Also with regard efficiency will there be a lot of power loss in the system? I don't really know how surge protection from overvoltage works in UPS's and assume it uses some kind of buck conversion...? I'm guessing that the surge protection circuits might struggle with continued voltage overload. Does anyone know if this would be the case? The question is, will the UPS's be able to reliably deliver either 230VAC or 48VDC?
