An evolution of the standby UPS, often used for small office networks.

Provides the highest level of protection against all power disturbances (noise, spikes, frequency shifts), but is more expensive and slightly less energy-efficient due to constant double conversion.

Low cost and high efficiency, but features a short "switching delay" (typically 4–10 ms) and no voltage regulation in normal mode. 2. Line-Interactive Scheme An evolution of the standby UPS, often used

Because the inverter is always active, there is zero transfer time when the power fails. An evolution of the standby UPS

The most advanced scheme, designed for critical equipment like servers and medical devices.
