Kronos UPS with Online topology, equipped with an inverter with up-to-date technology and high quality, is a good option for protecting sensitive consumers, especially in the field of information technology. This UPS is designed to take up as little space as possible; At 20 kVA with 40 internal batteries, it occupies only 0.22 square meters. The feature of power expansion or increase of system reliability (Redundancy) is available by parallelizing up to 6 UPS devices with the possibility of using common batteries. The four-and-a-half-inch color LCD display with Touch screen capability displays the values of various device parameters well. It is also possible to place the battery inside the UPS (up to 20 kVA) or provide it with a high current charger (custom equipment) to charge external batteries.
