When voltage falls outside a specific range or fails entirely, a mechanical switch transfers the load to the internal battery and inverter.
Better protection against brownouts than Off-line models, with a reduced frequency of battery use, extending battery life. 3. On-line (Double Conversion) Scheme shemy raboty ibp
The most advanced scheme, designed for critical equipment like servers and medical devices. When voltage falls outside a specific range or
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 shemy raboty ibp
