[mab1082]

Dear members and supervisors:

I hope I find what I can to help me solve my problem with the ups
In short my problem I owned a Model SUA3000XL and is now a dead sense of the word you disclose it and found the following:
1 - batteries carry voltage 5 V, and when you press the power button does not work as well as the device does not light up any bulb and do not hear any warning ..... Important for you to open the device and measuring the voltage inside the device and found 220 volts ....
After inspecting some of the components I did not find anything bad, I was no doubt in irf 740, irf 720 existing Department of shopper and after measurements of voltage and found that the effort is not up on both sides of Mosfet irf740 and I'm now confused as I do not have a schematic diagram for this device to trace the bugs you search for the schematic and have not found Can you find me that this scheme in order to repaired my beloved ..... and you link two specifications from the manufacturer
