Three typical requirements for batteries in the communication power supply industry

　　〔1〕 Communication DC Switching Power Supply System

　　Given the high reliability requirements of communication, a comprehensive communication power supply solution requires the switching power supply system to be equipped with batteries. There are various types of main communication equipment and ancillary equipment, and there are also many application areas for switch mode power supplies. The summary is as follows:

　　〔a〕 Outdoor base station;

　　〔b〕 Village communication and other base stations without air conditioning;

　　〔c〕 The indoor station space is compact;

　　〔d〕 Indoor coverage/distributed source station DC power supply;

　　〔e〕 Solar photovoltaic base stations without mains power or in Class III or IV mains power areas;

　　〔f〕 WLAN website and other DC power supply strategies.

　　〔2〕 Communication UPS AC power system

　　The UPS AC power system is mainly used for the main AC circuit part of the power supply system. The application of UPS AC power system in the communication industry is mainly as follows:

　　〔a〕 Indoor coverage/distribution stations for AC power supply;

　　〔b〕 Micro cellular stations provide AC power supply;

　　〔c〕 Embedded UPS power supply in the data center;

　　〔d〕 WLAN website and other AC power supply solutions.

　　〔3〕 240V/336V Communication High Voltage DC Power Supply System [HVDC]

　　Communication High Voltage Power DC System [HVDC] Currently, it is a new type of communication room power supply system, with supporting battery pack voltage levels of 240V and 336V, and battery capacity generally of 50Ah 200Ah.
