FEATURE

◆ 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.

◆ 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 off aulty 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 maintenance safely.

◆ 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.

◆ 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.

◆ 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)
