The UPS passes utility power directly to the connected equipment while simultaneously charging the battery.

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

Activates when utility power fails completely or fluctuates beyond the AVR's corrective range. The UPS passes utility power directly to the

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. Summary Comparison Table Off-line (Standby) Line-Interactive On-line (Double Conv.) Transfer Time 0 ms Voltage Regulation None (only on battery) Basic (via AVR) Perfect (constant) Best Use Case Home computers Small offices, workstations Servers, data centers Cost Provides the highest level of protection against all

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

Better protection against brownouts than Off-line models, with a reduced frequency of battery use, extending battery life. 3. On-line (Double Conversion) Scheme
