Line Interactive UPSs are more economical, producing simulated sine wave voltage while powering your load through the grid. In the event of a power outage, the UPS takes a few milliseconds to power the device from the battery (switching time). This is why Line Interactive is suitable for protecting devices such as Computer, TV, Security Systems and Cameras, Game consoles etc.
Online UPSs are more efficient, producing pure sinusoidal voltage, while directly feeding the connected load through the rectifier and inverter, resulting in zero switching time from the main grid. It offers continuous voltage stabilization, ensures continuous quality in the current supplied to the load and protects even the most sensitive devices. Online UPS are divided into categories according to the power supply to the grid that the UPS will support. Learn more here.
