The UPS Line-Interactive 1350VA 880W by CyberPower is a Tower UPS. Its operation is (VI) Line-Interactive, which continuously adjusts the output voltage through an automatic voltage regulator, protecting against voltage fluctuations and power outages. Its battery can last 8 minutes at half load or 2 minutes at full load (when the connected devices draw half or the maximum current that 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).
