Compared with Modular UPS, the Industrial Frequency UPS has fewer components, is the latter more reliable than the former one?
industrial frequency UPS mainly SCR rectifying (6-pulse or 12-pulse), poor performance on the input power factor, harmonic current and other electrical metrics, but its circuit configuration is relatively simple, after 30 years of development, technology is relatively mature. And because UPS generally has a long service life, some users will habitually choose the industrial frequency UPS that has been used many years ago when replacing it. High-frequency UPS has been on the market for more than ten years. At present, the technology of various manufacturers has been quite mature. In terms of circuit structure, there is not much difference in reliability compared with industrial frequency UPS.
As a new member of the high-frequency UPS family, modular UPS was introduced a little later, but because of its easy maintenance and other characteristics, the development is relatively rapid, and various manufacturers have also launched their own modular UPS.

The early modular UPS technology is not yet mature, especially the design defects of some manufacturers in control logic, mode conversion, failure exit, etc., leaving some users with the impression that the modular UPS is not highly reliable. In fact, after years of development, especially the application of various new devices and new technologies, the modular UPS of mainstream manufacturers has matured in technology and is relatively reliable in quality. In order to facilitate subsequent maintenance, more and more high-frequency tower UPSs are also adopting "modular type" technology (Learn the products that adopt this technology) in their mechanical structure.
It can be said that the form of the product is not a standard for distinguishing reliability. The reliability of the product is determined by the manufacturer’s attitude towards reliability and the degree of specificity, such as whether the system solution has sufficient redundancy, whether the application circuit is mature, whether the components are adequately retained, whether the production process and manufacturing system are complete, and whether the product delivery test is comprehensive and so on. The reliability of modular UPS is not worse than that of industrial frequency machines. At the same time, because of its modular structure, convenient maintenance and higher availability, it is more and more popular in the market. Therefore, the factors that determine whether a product is reliable depend more on the strength of the manufacturer itself.
