Line Interactive (VI) UPS

Line Interactive (VI) UPS systems provide reliable backup power and automatic voltage regulation, helping protect business-critical equipment from power interruptions, voltage fluctuations and common mains supply disturbances.

Line Interactive (VI) UPS systems provide an effective balance between power protection, operating efficiency and cost. By combining battery backup with Automatic Voltage Regulation (AVR), they help protect connected equipment from common electrical supply issues without unnecessarily switching to battery power.

Unlike basic standby UPS systems, Line Interactive UPS continuously monitor incoming voltage levels and automatically correct under-voltage and over-voltage conditions. This improves power quality, helps extend battery life and provides enhanced protection for equipment operating in environments where voltage fluctuations are common.

The Riello Line Interactive UPS range offers a cost-effective solution for protecting business-critical systems where a higher level of protection is required than a VFD UPS, without the complexity and cost associated with a fully Online (VFI) UPS system.
