Hi Ronnie,hi LIST,My friend brought me a used APC BACK-UPS 600 from USA. Upon openning the unit I found out that the two 6 volts battery are dead. I connected it to my 12Volts/ 150A/H truck battery and it works just fine but the output is 120 VAC. Any idea where I can find the schematics for this UPS so that I can convert it to 220VAC. Web searching gives no result. Thanks ===== Ronnie B. Tabanao Everything Electronics Services #06 Juan Luna St.,La Castellana,Negros Occidental 6131 Philippines
this is simplest thing, find 120v ->220v transformer. Connect it to output of the UPS. As this UPS was brought from USA. it may have 60 Hz output. Anyway, 50Hz transformer works also. the power will be a little bit less.
Happy New Year from Estonia!
