Description
The VFI scheme forms the output voltage with the inverter all the time, so the load does not feel sags, overvoltages and frequency deviations of the mains. The rectifier and inverter are built on IGBT transistors, and the control algorithms are run by a digital DSP processor. The compact design matters for machine rooms where a UPS of hundreds of kVA has to fit into an existing room together with battery cabinets. At such powers the unit stands on the busbars of the main panel and feeds whole rows of server racks or process lines, so its choice is agreed with the power supply project. The battery bank, the external bypass and the redundancy scheme are selected separately for a specific site and the required backup time.
How to choose
What decides here is the load power taking into account the growth of the site several years ahead. The range of 100–800 kVA overlaps with smaller three-phase series only in the lower part, so for medium electrical rooms X-TRA should be compared with X-PERT. If the data center power will grow gradually, consider the modular ADAPT2, where modules are added without switching off the load.

FAQ
What is the maximum power of the SLC X-TRA?
The series covers 100–800 kVA in a three-phase design with VFI double conversion.
On which power switches is the SLC X-TRA built?
The rectifier and inverter are made on IGBT, and the control is digital on a DSP processor.
For which sites is the X-TRA UPS suitable?
For large critical sites where a three-phase UPS of 100–800 kVA in a compact case is needed, for example data centers and large industrial enterprises.
How does the VFI topology differ from line-interactive?
In VFI the load is always fed from the inverter, and the mains through the rectifier only supply it and the battery. A line-interactive UPS passes the mains to the output and switches to the battery only in a fault.
Is a separate project needed to install an 800 kVA UPS?
Yes, at such powers the UPS is connected to the main panel, and the batteries, bypass and redundancy scheme are calculated in the power supply project of the site.
