Tower UPS
A standalone online double-conversion tower UPS from 1 kVA single-phase to 500 kVA three-phase, engineered to VFI-SS-111 with 0 ms transfer, high efficiency and parallel expansion for enterprise rooms, telecom sites and data-center loads.
Key applications: data-center and server rooms, telecom and network sites, banking and enterprise, healthcare.
Why Tower UPS
Online double-conversion
Pure online (VFI) topology to VFI-SS-111 with 0 ms transfer between mains, battery and bypass for clean, uninterrupted output.
1 kVA to 500 kVA
Single-phase 1–10 kVA and three-phase 10–500 kVA units cover everything from a comms room to a data hall.
Parallel & expandable
Parallel operation of up to 6 units with shared battery banks and LBS synchronization for capacity and redundancy.
High efficiency
Up to 96% online efficiency and ECO mode up to 99%, with input power factor >0.99 and current THD <3%.
