UPS

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?

Build a UPS

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?

UPS Battery

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 --------------------------------------------

UPS system

Hello every one recently i found a 12v 9000mah battery in my stuff and decided to make sth with it and found out that a UPS system can be good. I want to make a system that can give me power for a short time while I am outdoors so the low amper wont be a problem but I want to make the system with lower cost and better quality so I found out that I had to choose an inverter(12 to 220) which I think a 100w one would work. But my problem is choosing the inverter these are my choices based on my research:An inverter starter kit---------the cheapestAn inverter module(ones without box and fan which are small too)Inverters that are used in cars(ones with a box and fan)----------the most expensive

UPS battery backup as car inverter?

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! :)

Request: An Internal UPS or battery for a PC

My town has been experiencing power dips and short outages. i bought a cheap ups but it doesn't really do the job (the PC still cuts out) but i noticed that my laptop carries on just fine (obviously because it has an internal battery) so that got me wondering. Inside the pc it's just 12v and 5v isn't it? surely you could set up a battery inside the case that works just like the one in a laptop. anyone fancy giving it a go?

Can my UPS protect my TV and other Electronics other than my PC?

Hello, I've a recently bought an UPS "Solltek 1400VA/840W UPS" to help me supply my PC when the power cuts off... It works perfectly so far for my PC specially because it only supports the "IEC 320 C-13 C-14 Cables" Outlet which is Perfect for the Power supply Inlet of my PC... But furthermore, Can I use a converter to Convert that IEC C-13 to a Normal wall socket so that i can Plug any other Electronic device too (TV, Speakers, Printers, etc...) to work when the power cuts off.. ( a Converter like this one in the link http://goo.gl/D4mxkZ )  also i Wonder whether that procedure would be Harmful for those Electronic Devices or not (because of the Modified Sinewave type thing ..)

Home Electronic Project, Can Use Some Help :)

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

Home-made UPS? Answered

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?

Old UPS transformers: Any uses?

Does anyone know of a use for those massive transformers found in dead UPS's? Please don't post replies that include "door stop" or "recycle them" because those are obvious replies when you have no answer to my question. *SMILE* I have not tried but if the "secondary" for those that is the 110v output to the plugs were hooked to 110, do the original primaries become low voltage ac secondaries? (~12v) I have accumulated about 6 of these and would like to find an electronic use for them before resorting to recycle.  I have no doors that need propped open. Thanks.

How to get a UPS to turn on without being connected to AC? Answered

I want to use a UPS and a car/deep cycle battery to get AC power when away from outlets or when the power is off. ie what I want is to be able to have my UPs attached to a car battery and turned off and then when I want to use it turn on the UPS and have AC power. That would seem easy enough. But it doesn't work. My UPS works fine on the battery if it is connected to AC and then unplugged while turned on. 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. The black one is 650VA APC model. I would prefer to use the black one but I could use the white one. Thanks for any help. If you need more info just let me know.

Convert 320VDC to 230VAC or 48VDC voltage using 230VAC (UK) UPS?

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? Here are the specs for each individual panel; http://www.innoasia.net/2010/pdf/presentation/SmartCity_Takano.pdf Open circuit voltage(Voc): 429V Optimum power voltage(VMP):319 V Short circuit current(Isc): 0.39A Max operating current(IMP): 0.288A torrence:+_5% Maximum system voltage: 1000V THERMAL CHARACTERISTICS: (-25 ° C to +90 ° C) Temperature coefficient É‘Isc +0.08%/ ° C Temperature coefficient É‘Voc -0.35%/ ° C.
