The Premium VIS 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 Premium VIS UPS can work with a battery voltage of only 192 to 240Vdc (adjustable). This reduces space, batteries and price. Up to 4 Premium VIS systems can be connected in parallel to get maximum power capacity. Only one battery is necessary with the parallel mode.
