Review on Redundant UPS APC by Schneider Electric Back-UPS BE850G2-RS by Janis Endzelins ᠌

I bought APC for 30k, beautiful, silent, to this day pleases. Then I took another model for 60k, it ALWAYS makes constant noise from it, even if it is turned off from the outlet. After much deliberation, it turned out that this is normal. Then I bought this one for the TV. I have read positive reviews. In general, it also buzzes quietly if the power support function is enabled. Therefore, if you take somewhere near the workplace, be careful.
