Modular UPS-Kstar HPM  Family
In order to save the wasted power of underutilized, over-size ordinary UPS, and obtain "N + 1" redundancy to ensure the critical system has high power availability,  data centers now choose modular UPS as their first choice for critical power protection. With Compact size,high efficiency and easy expansion according to power requirements. Modular UPS systems are growing fast in the three-phase market.

HPM series UPS(Uninterrutible power supply system)efficiency can be as high as 96.5%,minimizing UPS energy consumption.The module capacity is 6KVA-50kVA optional. The UPS system consists of 1 to 20 UPS modules connected in parallel and the number of UPS cab be flexibly increased with load. The modular design and the N + X parallel redundancy technology, making the expansion&management easier as well as reducing initial acquisition costs.
General Features

● Adopting digital control design, and the control system is more reliable

● High power density design, capacity of single power module is 6KVA/ 10KVA/ 15KVA/ 20KVA/ 25KVA/ 30KVA/ 40KVA, the height of all these modules is 3U.The power of system ranged from 6KVA to 520KVA corresponds to the number of parallel power modules from 1 to 13

 Redundant control system, each power module is equipped independent control system, and control itself independently according to the sharing message, and the fault module separates from the system automatically

 Support parallel expansion for cabinet, and  parallel expansion is up to 4 cabinets.

 Voltage of batteries can be configured flexibly, 1 input 1 output/ 3 input 1 output ±96Vdc/ ±108Vdc/ ±120Vdc(16/18/20PCS)selectable; 3 input 3 output±216Vdc/±228Vdc/±240Vdc (32/34/ 36/38/40PCS) selectable

 Intelligent charging mode, Charging current can be configured , there are 3 charging mode  which are constant current mode、constant voltage mode、floating charging mode, and the charging mode can be transfer smoothly.
