Hello friends,
Sorry for writing in English and doing so with the help of ChatGPT — I’m from Argentina and my native language is Spanish. I hope you can help me. Congratulations on this forum, it’s a great resource for all of us who are trying to repair a UPS. I haven’t been able to find another forum as complete as this one, so thank you for existing.
I have an APC UPS SRT2200XLI with a damaged controller board. Someone kindly sent me a photo of the area where the damage is, but they omitted the value of an SMD capacitor and have not replied again. I would really appreciate your help.
If anyone has the schematic of this comparator stage, or if you could measure the value of the capacitor with an LCR meter or DMM, it would be extremely helpful.
I have uploaded the photos to Imgur, here is the link. You can see the damaged area as well as the reference photo I received, where I marked with an arrow the component whose value I need.
Thank you very much for your time and support.
