  • never seen bigest idiot:(

  • ZZZzzzzzzzzzz

  • Comment removed

  • Awwn awwff, awwn awff.

  • cheer up buddy

  • At least he's sharing info with those who might need it. Maybe a little disjointed and flat in presentation, but give him credit.

  • Optimus prime inside of his UPS,thumbs up xD

  • are you high? =))good shit bro :P

  • man are you sleeping or p...ping?.....you sound like you r triying to wake up....

  • Since I can see that you actually know at least somewhat how it works, it is annoying me that you speak that slow and screw a little around in what you say, which will confuse many people; if you're planning to make more videos I recommend that you write down what you want to tell and do a quick rehearsal of it. That will get you many many more views plus eg. this video would only have been half the length it is now.

  • wtf!

  • boring!!!! Yawn

  • I learned something today!

  • your explanation of the working of a ups is very good and clear good job

    i have at home a online ups of 4500W with 12 batteries of 40Ah it has a backup time of about 14 hours at a load of 18 A and 230V

    but i work on ups systems every day with a power between 500 W and 1500 KW so its my job

    your explanation is nice work

  • the transistor are basically electronic relays to switch the power on relays as electronics cant handle the voltage of mains and the current of the battery.

    So basically you go from a digital signal into electronic transistor which then switches the 12 volt relay( a digital signal cant switch the relay, it needs the transistor to act as a small relay to power up the coil in the 12 volt one)

  • @farcryaustralia Incorrect. Transistors are quite capable of switching high voltage/high current loads. There is at least one in your computer power supply operating at over 300V and several amps. Inverter welders such as the Miller XMT in my other video have very large transistors. On the highest setting, it produces 300A at around 80V.

  • @TheLightningStalker i was refering to the relationship between the transistors and the relays on the ups unit u have man ;) not giving you a hard time man just saying.

  • @TheLightningStalker by the term several amps! how many you actually mean man that is a lot of power!! for a computer that is :) 3 amps at 300 is like 900 watts? my psu is only like 550watt

  • @farcryaustralia At 500W, that would be maybe 2A through the transistor, though it is capable of much more. The Fairchild FQA9N90, used in some power supplies, can handle over 6A at up to 900V with adequate cooling. They use an oversized transistor for higher reliability and to get away with using a smaller heat sink.

  • @TheLightningStalker cool, thanks man :) that is good to know! I am new to this electronics thing but have known the basic for years just been watching some stuff on ups cause i want to set something up to run like 4 or more comps for multiple hours so I am researching what is in these things.

  • my ceiling fan sound gets more heavy while running on ups, is it normal?

  • @saifkhantube Yes.

  • @TheLightningStalker thanks mate

  • @Xearo167 If you can find a Back-UPS Pro 1000, that's the one to get.  Still, I don't think it has a much better charging circuit. It takes 2 batteries as well, so replacement is twice the price. That's why I recommend using deep cycle boat batteries with maintenance ports. That way you can refill with some distilled water when the electrolyte gets low.

  • I like your idea about car battery being used. It has more capacity to run a computer. But the charger of the circuit must provide same current rating for the battery so that it will not burn up easily... So I suggest that isolating a different charger would suit up to the battery... Anyway, thank you for this good video. It helps... thanks a lot...

  • @venghead1 There should be current limiting in the charging circuit to take care of that.

  • We had about 12 APC ups and I must say their quality is awful.

  • Cool video...but I cant get out of my mind that you sound like Crispin Glover. You're my density----lol

  • I have a tripp-lite AVR750U UPS and I disconnected it for about 3 weeks (it's over a year old). When I reconnected it, the power button would not turn on. It has 2 sides, one with battery backup and the other without. If i plug in a device on the side that doesn't have battery backup, it works...even though the UPS doesn't turn on. But the side that has the battery backup, doesn't seem to output any power. Is this a battery issue or could there be a problem on the circuit board? please help.

  • Good information, thanks for posting.

    Bill

  • Thanks for exlanation. I'm very interested in this way to provide energy to my tv and computer. I'll conect my battery car to the ups to give more time. I live in the mountain of México and the electrical service is very irregular when rains.

  • Tvs and Computers work very well on a UPS. Keep an eye on the water level in the cells of the battery.

    Cheers

  • I like you. You have helped me learned new things. keep making vids. And I saw the comment about your voice. Don't worrie what others think of you. Our differeceses are what make us who we are.

  • Cool, another informative video. I also have a dead UPS sitting in my shed waiting for repair. Only problem is - I had no idea how they worked. This gives me a great start, so thanks. BTW loved the Car Battery Idea. Also, I didn't know that the electrolites burn up in those sealed batteries, but it make sense when you

    think about it as no doubt they would alway be on charge.

  • Most likely, it's the battery. You can test it by connecting a 12V power supply in place of the battery. You could also hook it up to your car battery.
