The product combines the modular design with N+X parallel redundancy technology. The maximum capacity includes 50KVA and 100KVA which is convenient for flexible configuration. The UPS incorporates the industry-leading technology and ideas, and have done better in component selection, PCB layout, thermal design, control algorithms, appearance and etc.; the hot-swap technology is used between the module and the enclosure, which greatly reduce the maintenance time for system. It also adopts large touchable LCD and menu design, so all the information about UPS can be monitored through the LCD, which helps to get the operation clearly; each module has both the LCD and LED display, which allows the users to get the working status and operating parameters intuitively. The UPS adopts the advanced DPS digital control technology. Each module uses a separate control panel, so it will easily remove from the UPS system when it is failure, which makes the system more stable and reliable.
