Online (VFI) UPS

Online (VFI) UPS systems provide the highest level of power protection, continuously conditioning incoming power to protect critical equipment from outages, voltage fluctuations, frequency variations and electrical disturbances.

Online UPS, also known as Voltage and Frequency Independent (VFI) UPS, use double-conversion technology to deliver the highest level of power protection for business-critical and mission-critical applications.

Unlike standby or line interactive UPS systems, Online UPS units continuously regenerate the output power supply through an inverter, isolating connected equipment from mains power disturbances. This helps protect sensitive electronic systems from voltage fluctuations, frequency variations, harmonics, electrical noise, surges and power interruptions.

The Riello Online UPS portfolio includes single-phase and three-phase solutions in tower, rackmount and modular configurations, providing reliable power protection for applications ranging from small server rooms through to large industrial installations and data centres.

Online UPS systems are widely used where continuous operation, maximum uptime and power quality are essential.
