Price-performance Ratio

The VFI 10–40 kVA TC series is our best “price-performance ratio” 3/3 phase UPS. Based on our modular UPS technology, we are able to offer extremely small UPS 10-30kVA solutions. A combination of our modular based UPS with a special DC/DC converter, the VFI TC UPS can work with a battery voltage of only 192 to 240 V DC (adjustable). It allows to reduce space, batteries and price.
