Line Interactive vs Online UPS: which Apollo system do you need?

Not every load needs the same UPS topology. Line Interactive units are cost-effective for PCs and networking gear, while Online UPS systems deliver clean, zero-transfer power for servers and industrial controls.

Line Interactive UPS corrects mild voltage swings with AVR and switches to battery when power fails—ideal for desktops, POS, and small offices.

Online UPS continuously converts AC→DC→AC, isolating sensitive equipment from noise and providing seamless backup for data centers, medical devices, and production lines.

• Choose Line Interactive for PCs, routers, and retail tills
• Choose Online UPS for servers, PLCs, and critical infrastructure
• Match VA rating to total load plus 20–30% headroom
• Plan battery autonomy for your expected outage window
