The Smart-UPS SC420I Line-Interactive 420VA 260W with 3 IEC Power Plugs by APC is a Tower UPS. It has 3 outlets of type IEC (such as those for computer power supplies) as well as an input and output for an ethernet cable, protecting devices connected to it, such as a router (provided their power is connected to a UPS or surge protector). Its operation is (VI) Line-Interactive which continuously adjusts the output voltage through an automatic voltage regulator, 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 active PFC protection (e.g. computers).
