Line Interactive UPS
A line-interactive UPS is a device responsible for maintaining the inverter in line while redirecting the battery’s direct current from the standard charging to supplying current. It is beneficial only when the power is lost, and it transfers the power from the battery to the UPS output. The typical design of line interactive UPS offers additional filtering that yields reduced switching transients. So, these are the cheapest option than investing in online double conversion technology. The line interactive UPS can protect the critical load from power sags, failures, surges, and even voltage fluctuations.
