Technical characteristics of high-power UPS power supply and low-power UPS. According to the power of UPS power supply, it can be divided into three partition categories: large, medium and small. Small power UPS power supply system is defined as a power supply product with a power of less than 3kva. The sales proportion of high-power UPS power supplies above 10KVA in the domestic market increased from 70% in 2014 to 76% in the first half of 2016. It is expected that the growth rate of high-margin high-power UPS will be significantly higher than that of the industry in the future, with high-power UPS exceeding 50% market share.

　　1. High-power UPS power supply

　　High-power UPS power supply dedicated to large computer rooms is mainly used to provide stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc. High-power UPS power supply is a new generation of purely online intelligent UPS power supply developed using new digital technology for China's power grid environment and high-end power consumption occasions.

　　The high-power UPS power supply system adopts an online double-conversion topology design, which completely eliminates interference from the power grid. The rectifier adopts three-level PWM rectification technology based on IGBT devices, achieving superior performance of high input power factor and low input current harmonics. The inverter adopts pulse width modulation technology based on IGBT devices and is equipped with an output isolation transformer, which enables the output of the UPS to achieve stable frequency and voltage, low waveform distortion, strong load capacity and strong impact resistance.

　　Technical characteristics of high-power UPS power supply

　　Three inputs and three outputs, supporting 380/400/415V, 50/60Hz power grid system

　　Pure online double conversion, providing the best power supply quality

　　With mixed load capacity and high overload capacity

　　The battery is directly connected to the busbar, and the output has good impact resistance.

　　Unique ventilation design, compact structure and small size

　　The output isolation transformer adopts DZn winding method and has strong unbalanced load capacity.

　　The input and output are fully isolated, and there is no danger of DC series input to the load, which is highly safe.

　　DSP fully digital control realizes all digitalization of IGBT rectifier and inverter converter

　　The latest IGBT rectification technology, input power factor up to 0.99, low harmonic current

　　Green, environmentally friendly, efficient and energy-saving

　　2. Low power UPS power supply

　　With the accelerated development of emerging technologies such as cloud computing, big data, and the Internet of Things, all industries are adapting to the development trends of the times and improving the efficiency of their digital transformation through various effective measures. The market development of small and medium-power UPS, which has important application value in industry informatization, has also shown a strong growth trend. Objectively speaking, based on the growth of application demand, the market value-added space of small and medium-power UPS is unlimited, which is fully reflected in the expansion of user volume and market scale.

　　As the mainstream customers of small and medium-power UPS power products, customers in important industries such as finance, communications, transportation, IT, government, education, and medical care account for almost half of the UPS application market. Industry customers' demand for small and medium-power UPS power supplies focuses on upgrading existing products and meeting new business needs. This not only promotes the continued expansion of the market size of small and medium-power UPS, but also puts forward higher requirements for product applications.

　　Customers' core requirements for UPS power supplies have always focused on the actual performance of the product, and this is even more obvious in small and medium-power UPS applications where the needs are more refined and the application scenarios are more complex.

　　Technical characteristics of small and medium power UPS power supply

　　Breakthrough ultra-compact design: 30% to 70% smaller than similar products;

　　Large-screen LCD display makes settings more direct and convenient;

　　Within the input voltage range of 120~288V, the output is not derated, which greatly reduces the probability of battery transfer and increases battery life;

　　Strong overload capacity: Under the mains power rating, 130% can be used for 10 minutes, and 150% can be used for 1 minute, meeting the customer's sudden load requirements;

　　8A long-term charging capacity, the charging capacity can be set to meet the rapid recharge of long-delay batteries and improve battery life;

　　With excellent environmental protection and energy-saving features, the efficiency is 3-4 percentage points higher than similar products. A full load of 1K can save nearly one kilowatt hour of electricity a day.

　　Low-power UPS power supplies and high-power UPS models each have their own characteristics. We focus on many aspects such as high maturity, scalability, redundancy, overall machine efficiency, input harmonics, PF index, floor space, and rapid maintenance. Compare.
