The Smart-Ups Srt 2200VA UPS On-Line 1980W with 10 IEC Sockets from APC is a Tower UPS. It features 10 IEC type sockets (like those of computer power supplies) as well as an input and output for an ethernet cable, protecting the devices connected to it, e.g., a router (provided that their power supply is also connected to the UPS or a surge protector). Its operation is (VFI) On-Line/Double Conversion, which continuously provides power from its battery, protecting against voltage fluctuations and power outages. Its battery can last 11 minutes at half load or 3 minutes at full load (when the connected devices draw half or the maximum current the UPS can provide, respectively). It offers pure sine wave power, which is suitable for sensitive devices (e.g., medical equipment) and is preferred for devices with power supplies that have active PFC protection (e.g., computers).
