The VFI 3000 ICT IoT UPS On-Line 3000VA 3000W with 8 IEC Outlets from Powerwalker is a Tower UPS. It features 8 IEC type outlets (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 their power supply is also connected to a UPS or a surge protector). Its operation is (VFI) On-Line/Double Conversion, which continuously supplies power from its battery, protecting against voltage fluctuations and power outages. It provides 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).
