　　Modular UPS power supply system solution. The modular UPS power system is the data center infrastructure. It has core technologies such as modular UPS, intelligent power distribution management and integrated control of lithium iron phosphate battery UPS. We have developed an intelligent, integrated and modular system suitable for data centers. UPS power system. Adopting a 5.7-inch touch screen LCD design and menu structure, various UPS information can be monitored through the LCD, making all operations clear at a glance.

　　Modular UPS power supply system solution

　　The modular UPS power supply system is the core of the entire data center. The redundancy and future expansion of the UPS system must be considered, so a redundant structure needs to be adopted. The UPS power supply adopts a modular, hot-swappable, redundant parallel design of power modules, and is equipped with a set of 60-minute batteries for a 32KW load. It can also support the load and provide delay when one or even multiple power modules fail. According to the technical requirements, the UPS system has a backup of 32KW for 1 hour. This plan uses a set of its CUN-M series modular UPS power supply and distribution system. The UPS host computer and battery cabinet adopt standardized cabinet design to reduce the floor space.

　　The UPS with modular and hot-swappable structure is completely designed in accordance with the ideas and structure of IT equipment. The power modules are redundantly connected in parallel output. The control part adopts redundant design of two sets of hot-swappable control modules and two sets of logical low-voltage power supply modules. High availability. In addition, because the modular hot-swappable structure can easily add or remove various modules online to increase output power or repair, it has advantages that traditional 1+1 parallel connection cannot match in terms of availability, maintainability, and capacity expansion.

　　CUN-M series industrial-grade modular UPS power supply is a high-end modular UPS product. It not only includes the rectification, filtering, charging, and inverter devices of traditional UPS, but also has intelligent power protection functions and adopts It has adopted many new concept technologies such as average current control rectification technology, sequential master-slave synchronous control technology, multi-level distributed control technology and third-order sine wave inverter, which has greatly improved the availability and reliability of the equipment and reduced the cost. Equipment investment, operation and maintenance costs.

　　The system capacity includes multiple systems of 100KVA, 150KVA, 200KVA, 240KVA, 320KVA, and 480KVA. The power modules are 10KVA, 15KVA, and 20KVA. Users can choose at will according to the load size. It has complete battery management functions: battery self-discharge function, automatic equalization and floating charge conversion function, temperature compensation function, and automatic current sharing function. If the actual load increases, power modules can be added to expand the system capacity to 48KW, ensuring the safety and redundancy of the system while avoiding inefficiency and waste caused by investing too much capacity in the initial stage.

　　According to the requirements, the design is as follows, with a total of 3 cabinets, one UPS main cabinet (including UPS input and output precision power distribution), and two battery cabinets. The battery cabinet can choose a modular UPS battery cabinet. The cabinet is black and has a 19-inch rack-mounted appearance. Like the server cabinet, it can be placed directly inside the cabinet to improve system reliability. Modular UPS power supply can be flexibly configured and has strong scene adaptability; the computer room has high floors and low load-bearing requirements, which can meet various computer room construction and renovation scenarios. The modular solution, single and double row construction, flexible expansion of the number of counters, and adaptability to a variety of Scenario requirements.

　　The network architecture is modular, with servers, micro-modules and their infrastructure suitable for specific business implementations. Factory prefabricated, on-site assembly, rapid deployment. Standardization and productization of components, high-quality control capabilities and clear engineering interfaces. It changes the way the system cools. Inter-rack cooling to meet medium to high power density room requirements. The micro-module is composed of two rows of opposite equipment units. The sealing components of the channel, skylights, side doors, etc. realize the isolation of hot and cold channels. It comes with an uninterruptible power supply. Different micro-modules can be powered by different energy systems, allowing multiple power supply combinations in the same room for easy disassembly and assembly. Micro modules are factory-prefabricated, industrialized and standardized, and can be easily disassembled and assembled. The construction time is short and the construction site is easy to manage.

　　Advantages of modular UPS power supply

　　⒈A variety of working systems

　　The modular UPS has a variety of formats to choose from, is easy to operate, and can realize a variety of incoming and outgoing lines: 1/1, 1/3, 3/1 or 3/3. The input frequency can be 50Hz or the output frequency can be set to 60Hz. The output voltage can be set to 220V, 230V, 240V. If input and output transformers are configured, it can meet the power supply needs of all countries and regions around the world.

　　⒉Small size and high power density

　　This product has high working efficiency and high power density, which are its biggest features. The size of a power module is: (H×W×D) mm: 133×482×46, which can provide power output of 5KVA (4000W), 10KVA (8000W), 15KVA (12KW) and 20KVA (16KW).

　　⒊Environmental protection

　　UPS total harmonic distortion (THDI) is 3%, and the output total harmonic distortion under linear load is less than 2%, minimizing harmonic interference to the power grid, effectively reducing grid load and power loss. Excellent input parameters, showing pure resistance characteristics to the mains power grid, is an ideal environmentally friendly and efficient UPS.

　　⒋High efficiency and energy saving

　　Today, when the country advocates environmental protection and energy conservation, the green and energy-saving modular UPS power supply has attracted much attention, with an input power factor of over 0.999. Reduces line losses and improves power utilization. Its inverter efficiency can reach more than 98%, thereby improving the working efficiency of the whole machine, reducing losses and saving electric energy.

　　⒌Extensibility, easy to install, maintain, replace and upgrade

　　This model is composed of various modules, which can realize hot-swappable function, and the racks of each module can be completely separated, which facilitates the user's future expansion or reduction. It is easy to use and can realize online replacement and online maintenance, which reduces the difficulty of maintenance and reduces the cost of maintenance. maintenance time. And the size of each module is designed according to the standard 19-inch structure, making the appearance of the whole machine consistent with the standard rack, beautifying the appearance of the machine, and the modules can be used universally with the standard rack.

　　⒍Redundancy, distributed parallel logic control

　　The parallel control between each module adopts a decentralized logic control method. There is no distinction between master and slave. The removal or insertion of any module will not affect the normal operation of other modules. N+1, N+X can be formed as needed. The redundant system reduces the risk coefficient of the system itself and the load, and comprehensively improves the load protection time by UPS. It not only increases the reliability of the whole machine, but also simplifies the difficulty of user maintenance.
