I practically blow up my UPS (1200VA-720W) 1 week ago.
I wanted to attach a led to the main board and probably (i am not sure) my thick copper soldering tip melted 2 very close nodes together, OR the flux made a capillary connection between 2 very close nodes; and short circuit some SMD and normal components on the main board, with sparks and smoke. My morale was -10 at that point. I asked the repair company if they can send me a new electronic board and they just play dumb. Ok... so I have 2 good accumulators, 1 good transformer, some wires, the LCD display, and the case.
I was thinking today if is possible to build myself the board !
My electronics skill is medium, I know some stuff, but i am not an engineer. I am a electronic hobby guy - tinkering in 30 years of my electronic life. I also lack some fundamentals too, I admit it. But I am not a rookie!
So, please tell me there is a chance to undo my mistake. Tell me there is a second chance.
While the board was working, and I was hunting for nodes of lower voltage to attach my led, I realized how this thing is working. Basically, when charging, (alternative) ~220V enters in transformer primary, ~24 is output in secondary, some components (i've seen a bridge there with large transistors and large aluminum radiators) transform it into || (continuum) 24 and split it by 2 >> 12 for each accumulator. When the Power is down, 24 || continuum is transformed into (alternative) ~24, goes back into transformer and out to power my computer. The thing is that it also powering my computer while charging also. This is what i observed by myself, i didnt read anything about it.
- I would like to make myself the schematic (very straight forward) if is possible.
OR,
- to buy a ready made alternative board for a general UPS?
What are your suggestions?
Thank you.
