Description

Up power supply

Technical Field

Background

With the continued evolution of technology, public power distribution systems have been quite reliable. However, research has shown that even the most perfect commercial networks are not possible to fully meet the requirements of those important data processing operation centers that are not intermittent. In the face of a situation where mains power and human operation may cause downtime and data processing errors, most companies choose to install an uninterruptible power supply (Uninterruptible Power Supply, UPS) system between the public power distribution system and its critical loads. The choice of what ups system design configuration scheme to choose for an application environment directly affects the availability of IT devices in the application environment. There are a variety of factors that affect the usability of the system, including human error, reliability of the device, maintenance level, and recovery time, among others. The impact of each of the above factors on the availability of the overall system is largely determined by the configuration scheme selected.

The prior art ups power supplies typically include back-up, online interactive and online ups, with the appropriate type being selected based on load requirements and budget. The UPS power supply configuration scheme includes a centralized or decentralized configuration, where the centralized configuration is suitable for devices to centralize and unify use of the same kind of UPS system, and the decentralized configuration is suitable for situations where the devices are decentralized or require different types of UPS. The traditional ups power source fails and must be checked and maintained by after-sales personnel of a ups power source manufacturer, and a bypass is required to be turned during the checking and maintenance, for example, the commercial power is powered off, so that the system cannot work. Therefore, the existing ups power supply has poor flexibility and more complex maintenance, and a user cannot flexibly select, replace or add modules according to own requirements so as to realize flexible configuration of the ups power supply.
