Communication system reliability requirements for high room, whether it is a large exchange of the station, small and medium exchange the station, or base stations, require high reliability power supply system, through the rational design of power system, the discrete components reliability assurance, and redundant configuration, communication systems can achieve the high demand for power supply system. Picture shows a typical example of a solution, the energy of the system together to provide mains and generator, and some places even have dual mains input. After ATS automatic switch to provide power to low voltage distribution after the system. In addition to the low voltage distribution system downstream of the AC power distribution system, but also undertake to supply air conditioning equipment and other tasks. Surge suppressors and other devices mounted at the same time. Low-voltage power distribution system into the AC distribution system, assigned to the UPS uninterruptible power supply systems, and communications power systems. UPS system to undertake the important task of sharing the load of the power supply, communication DC power supply system to undertake the task. Through dual modular redundancy configuration, UPS systems can reach higher than the traditional stand-alone system reliability and availability. Case based on the user’s site, UPS system output modules AC power distribution system may be configured to meet the needs of a variety of important load distribution. In order to ensure that fire and other emergency needs of low-voltage distribution system in the downstream EPS emergency power supply system configuration to ensure that fire pumps, fire lighting, elevators and other equipment, emergency power supply.
