On-line double conversion UPS with DSP microprocessors for precise, constant control of all measurements and of the power factor correction circuit (PFC). Transformer-free technology for high quality energy output with up to 96% efficiency.

VFI Single-phase online double conversion ups systems from 10 KVA to 60 KVA

VFI Three-phase online-double conversion UPS systems from 100 KVA to 800 KVA
Modular UPS enable the power supply to be sized exactly to requirements, without precluding any future expansion. They are made up of “standard” modules that can be added to existing configurations to increase their power or backup time. Their innovative modular system, provides the highest possible level of redundancy.
