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 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

[TheLightningStalker]

@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.

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

[TheLightningStalker]

@saifkhantube Yes.

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.
