I recently purchased an APC Back-UPS RS 1200G and have been using it to power my home office setup. While I’ve been impressed with its reliability, there’s one issue that’s been on my mind: an unusual electric arc noise coming from the unit during power outages. I wanted to share my experience and the steps I took to address it, in case others are facing a similar situation.When the power first cuts out, my computer seamlessly switches to battery power, but I notice a distinct buzzing or arcing sound coming from the UPS. At first, I was concerned this might indicate a serious issue, especially since I have a background in electronics and understand the potential risks involved with electrical equipment. My initial thought was to reach out to APC/Schneider for clarification.I contacted their support team here in Greece and spoke with a technician who assured me that the noise is normal and not a cause for concern. While this was somewhat reassuring, I wanted to dig deeper to ensure my setup was safe. I decided to conduct my own research and reached out to APC directly through their official website to get a formal response.After some back-and-forth, APC confirmed that the noise is indeed a normal operational characteristic of the unit. They explained that it’s related to the way the UPS manages power transitions during outages. While this doesn’t entirely eliminate my concerns, knowing that it’s a recognized feature has helped me feel more confident in the unit’s reliability.For anyone else experiencing similar concerns, I recommend reaching out directly to the manufacturer for clarification. It’s always better to be safe than sorry, and getting an official response can provide peace of mind. Additionally, I’ve started monitoring the unit more closely and have set up alerts through my home automation system to notify me of any unusual activity.Overall, I’m still satisfied with the APC Back-UPS RS 1200G. It’s been a reliable addition to my home setup, and the minor noise issue hasn’t impacted its functionality. I hope sharing my experience can help others who might be in a similar situation!
