A Line Interactive UPS (Uninterruptible Power Supply) is a device that provides backup power and surge protection to connected equipment during electrical outages or fluctuations. It typically utilizes a battery and inverter system to maintain power supply, allowing for seamless operation of critical devices. The line interactive design includes an automatic voltage regulation feature that helps stabilize voltage levels without switching to battery power, enhancing efficiency and prolonging battery life.
| Input Voltage Range | 170V to 280V |
| Output Voltage | 220V or 230V |
| Battery Type | Sealed lead-acid or lithium-ion |
| Power Rating | 500VA to 3000VA |
| Transfer Time | 2 to 10 milliseconds |
