What should I pay attention to when buying UPS power supply?

　　Now, data centers are becoming more and more important. How to ensure the stability of the company's data center has become a very critical element. UPS is currently the standard accessories of many companies in the data center. So what should I consider when choosing a suitable UPS power supply? This article will analyze this.

　　1. Input voltage

　　The wide input voltage range can meet the requirements of my country's power grid. The input voltage range of high-power UPS can reach -30% ~% 15% of the additional input voltage, which represents today's highest technical level.

　　2. Power supply reliability ofUPS power supply

　　UPS touches disciplines such as electrical electronics and data. The progress of uniform single -machine non -failure is limited by the theory of related disciplines and semiconductor data. At this stage, it is difficult to make breakthroughs, that is, UPS technology is in a sophisticated stage. The redundant technology in the UPS power system is an important way to improve the reliability of the UPS system.

　　UPS's reliability = unexpectedly redundant stand-alone uniform time without failure = 20-250,000 hours.

　　UPS's redundant power distribution method is nothing more than 1 1 (tower machine) or maybe N X (module machine). The tower machine consists of a rectifier, inverter, static switch, and control circuit. The module is composed of racks, UPS power modules, static switch modules, display communication modules and battery packs. Tower machines are mostly used by 1 1 redundant system, which is low, and the modular machine can achieve the N X redundant system without single -point fault bottleneck. Therefore, modular UPS is the best choice for data center reliability.

　　3. The scalability of the power supply

　　Considering the load for the current needs, and the scalability is for the future. Considering the needs of future transactions for systems, if you want to increase your power of your UPS system with practical needs, when buying UPS, you must focus on the scalability of the UPS power supply. By analyzing, the induction characteristics of module UPS power can maximize the reliability and availability of the system.

　　4.UPS energy use power

　　The practical power of UPS is determined by the load: when the load is 50%, the overall power is 70%, the load is 60%, and the overall power is 80%. If the traditional tower is reduced once at 1/1, each device is 50%of the device, but the power is 60%, which is already a manifestation of a low energy consumption ratio. During normal operation, modular UPS can configure reasonable power capacity according to the practical load configuration, and leave 2 to 4 redundant power modules, which is undoubtedly convenient and efficient.
