The VI 1500 R1U UPS Line-Interactive 1500VA 900W with 4 IEC Power Plugs by Powerwalker is a Rack UPS with 4 outlets of type IEC (such as those for computer power supplies). Its operation is (VI) Line-Interactive which continuously adjusts the output voltage through an automatic voltage regulator, protecting against voltage fluctuations and power outages. The battery can last for 8 minutes with half load or 0 minute with full load (when the connected devices draw half or maximum current that the UPS can provide respectively). 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).
