APC Back-UPS CS 350/500 (BK350EI/500EI) schematic
I am after a schematic for an APC Back-UPS CS 350/500 (BK350EI/500EI) unit.
The main board is a 640-0245 or 640-0245C. Searching for these numbers revealed a minefield of Russian websites with this information, but I could not access the schematics. I probably have to register to access this information.
Can anyone help with this schematic?
Interestingly, the mains is monitored without any transformers, and the battery negative is connected to the mains earth via a choke.
