How to ensure the modular UPS with high reliability

Modular UPSs have more than ten years of history, and have been widely used in large data centers thanks to their features of high availability, high scalability, easy maintenance, high efficiency, and many other advantages. The reliability of a modular UPS primarily depends on the system architecture design which should be simple and decoupled to avoid single points of failure. Key parts such as power modules, control modules, the system communication bus, power supply, and fans must be redundant. The UPS system reliability also depends on the system fault detection and isolation mechanisms, which ensure that a faulty unit is promptly detected and automatically isolated from the system so that remaining operational units can continue supplying power safely. Lastly, real-time detection and health condition evaluation of vulnerable devices ensure long term reliable operation of the power supply system. Leveraging its powerful and professional test verification platform, Huawei verifies and optimizes its modular UPS products through 21 special reliability tests, ensuring strong UPS adaptability to power grids, various environments, and loads.
