Best price-performance ratio

The IRIS+TT series is our best “price-performance ratio“ 3/3 phase UPS. Based on our Helios 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 IRIS+TT UPS can work with a battery voltage of only 192 to 240Vdc (adjustable). This reduce space, batteries and price.

Parallel mode

Up to 4 IRIS+TT systems can be connected in parallel to get maximum power capacity. Only one battery is necessary with the parallel mode.
