Modular UPS RM 50-600KVA

1. High Reliability 

●N+X   parallel redundancy design, and the system availability up to 99.999%. MTBF   lasts more than 250,000 hours to meet the high reliability demand of the   power supply system for critical loads. Flexible parallel redundancy setting   enable the system to provide maximum output capacity. 

●Parallel   redundancy of control system: The control mode is divided into decentralized   control and centralized management. The centralized control unit is connected   in parallel for redundancy, and a fault does not affect the operation of the   whole machine. Optimised distribution and combining cabinets ensure the   safety of parallel systems. 

●The   centralized monitoring module is hot-swappable. After removing the monitoring   module, the system can work normally. The use of centralized bypass power   supply can improve the power supply capacity. 

●EPO function: Press the EPO button urgently to shut down in an emergency; the   EPO button is designed for protection and avoid misoperation; it has a remote   emergency shutdown (REPO) function. 

2.   Convenient and Fexible 

●Modular design, consisting of 1~12 modules in parallel, with a   maximum power of 600kW, users can gradually increase the number of modules;   using hot-swap technology, modules can be added online and pulled out online   to achieve "zero" maintenance time. 

●Maintenance downtime is short. When the number of faulty modules is less than   the number of redundant modules, the downtime is zero. But if the number of   faulty modules is more than the number of redundant UPS modules, the   maintenance time will not exceed 5 minutes. 

●The LCD touch screen of the cabinet provides rich UPS status information,   warning information, fault information, etc. With single-module LCD, users   can better understand the working status of the module through the module LCD   light. 

●In an emergency, the UPS can be switched to the maintenance bypass for power   supply, and maintenance personnel can perform online mainte

3.Advanced Technology 

●The structure of each part adopts digital control, with excellent   performance, high system stability, self-protection and fault diagnosis   capabilities, avoiding the risk of operating device failure, and making the   control system more stable and reliable. 

●Using advanced three-level technology, the efficiency of the whole machine is   as high as 96%. 

●High power density design, 50kW single module, size (WxDxH) 440x620x130mm.   The output can be connected to a completely unbalanced load. When the output   is connected to an unbalanced load, the input current is three-phase   balanced, which can balance the load of the three-phase grid. 

4.   Intelligent Design 

●The charging current can be set, and the user-configured battery capacity and   charging current can be set through the panel LCD; automatic and smooth   switching between constant voltage charging mode, constant current charging   mode and floating charging mode is realized. 

●The intelligent charging mode adopts an advanced two-stage three-stage charging   method, which can well take into account the goals of fast charging and   prolonging battery life, saving users' battery investment. 

●Provide   a wealth of optional accessories, users can choose to install optional   accessories such as isolation transformer, power distribution board, SNMP   card, relay dry contact card, etc. to form a small and medium power   distribution system. 

5.   Green and Environmental Protection  

●The standard cabinet is adopted, which perfectly matches the application   environment of the computer room and saves the area. 

●Parallel   machine with battery sharing greatly reduces the number of battery   configurations, and users can configure batteries according to backup time. 

●The number of optional external battery, the users can choose accorrdingly   30/32/34/36/38/40/42/44/46/48/50 (30-50pcs optional)
