In normal operation, the Online UPS sends power to the AC load through the Rectifier and Inverter Combo, and during a power outage, it employs an inverter to supply AC power. As a result, the output power supply is always on and no switching is required. As a result, switching between its sources takes no time. Even if the power goes out for a moment, there is no disruption. If you want to know more about Online UPS and its functionalities, please check the blog.
