Hi,

I am wondering if someone with this UPS can give me the specifications of the red metal film capacity in the top right hand corner of the board (see attached photo)? I have a damaged unit with that capacitor broken off and want to repair it.

Also what is the difference between the units that have two 4,000uF caps (the big blue ones on the right) vs. the ones that only have 1?

Thanks,

Barry
