There is a certain relationship between the output quality and price of high-frequency online UPS, but it is not a simple direct proportional relationship. The following is a specific analysis:
Both technology and design have an impact: High quality high-frequency online UPS typically adopts more advanced technology and design, such as high-precision DSP digital control technology, active input power factor correction (PFC), etc. These technologies can improve the accuracy of output voltage, reduce output voltage waveform distortion, and make the output power purer and more stable. The high-frequency online UPS of Uber, with an output voltage of 220V ± 1% and a THD of only 1.5%, can effectively ensure the stable operation of scientific research equipment. Due to its high technical content, the price of such products is relatively high.
The quality of components affects both: using high-quality components is one of the key factors in ensuring output quality. Better quality components such as capacitors, inductors, IGBTs, etc. can withstand higher voltages and currents, reduce the probability of faults, improve the reliability and stability of UPS, but also increase product costs, thereby affecting prices. For example, some high-end high-frequency online UPS systems use IGBT as power conversion components, which have good high-frequency switching characteristics, can improve the efficiency and output quality of the inverter, and the price will correspondingly increase.
Manufacturing processes and quality control affect both: strict manufacturing processes and quality control systems can ensure the consistency and stability of high-frequency online UPS performance, reducing quality defects caused by production process issues. This requires companies to invest more manpower, material resources, and time costs, which will also be reflected in product prices. Like Huawei's UPS2000-A-1KTTL, it has an intelligent management system and a built-in LCD screen that can display the real-time operation status of the UPS, requiring higher process standards and quality control during the manufacturing process.
Brand factors affect price: The high-frequency online UPS of Yunhai Zhicheng Electric brand usually has more sufficient guarantees in research and development investment, technical support, after-sales service, etc., and its product quality is also more recognized by the market. There are certain advantages in quality assurance and comprehensive services.
