TP48300B/TP48600B电源系统是AC/DC室内电源系统，单机采用48V/30A或48V/50A整流模块，能够为-48V系列的通信设备提供稳定可靠的直流电源。

TP48300B/TP48600B电源系统解决方案基于站点的节能减排需求，符合现在倡导的绿色能源发展趋势，支持模块休眠和远端监控功能功能，减少基站能源建设总的投资成本，有效地减少站点巡检次数，降低运维

TP48300B/ TP48600B电源系统通过调整安装的整流模块数量可灵活应用于室内基站、室内中心机房等场景。电源系统安装方式为落地安装于机房内，支持靠墙（离墙壁距离≥100mm）。

电源系统都是由直流配电、交流配电、监控模块和整流模块4部分组成

最重要的对外接口就是直流输出配电

对于标准化机柜，上进线上出线方式应用场景最多

交流配电部分主要由空开和防雷两部分组成。

直流配电部分主要由空开、熔丝和直流防雷器三部分组成。

主要功能

直流输出管理：输出电压管理，负载均流，休眠功能

蓄电池管理：均、浮充管理，限流调压，温度补偿，电池测试，负载上下电管理

告警管理：识别并存储告警，通过干接点或通讯方式上报

环境监控：环境温湿度，蓄电池温度

远程监控：干接点，RS232/RS485，SNMP

监控模块可以通过实现本地操作、后台网管等方式实现环境监控、异常告警、电池管理、整流模块及配电管理等功能。

硬件架构——整流模块

整流模块（PSU）将输入的AC转换成稳定的-48V DC，华为常用的整流模块规格有30A、50A和100A。

电源模块散热方式均为强迫风冷，前进风、后出风。

电源模块支持热插拔，前维护。

当前业界整流模块的效率在90-94%之间，Eltek推出了96%的高效率电源模块。

LLVD低压保护电路工作原理

防止电池深度放电

电池的过度放电会导致电池的永久损坏。如2V电池的电压如放电下降到1.8V之后电池会永久损坏。

 延长传输设备使用时间 

考虑到部分负载在网络中处于关键位置，可采取分二次低压隔离切换。例如选择电池电压在46.5V时先关断一般性负载分路，到电池电压继降到44V时再关断其余重要负载分路。 

系统设置的BLVD电压值默认为43.2V，LLVD电压值默认为44V。

寿命>50万小时

支持远程管理与升级

30A/50A模块混插，保护投资

The TP48300B/TP48600B power supply system is the AC/DC indoor power supply system. The single machine uses 48V/30A or 48V/50A rectifier modules to provide a stable and reliable DC power supply for the communication equipment of the -48V series.

The solution of TP48300B/TP48600B power system is based on the energy saving and emission reduction demand of the site, which is in line with the green energy development trend advocated now, supports module dormancy and remote monitoring function, reduces the total investment cost of the base station energy construction, effectively reduces the number of site inspection and reduces operation and maintenance.

The TP48300B/ TP48600B power system can be flexibly applied to indoor base stations, indoor computer rooms and other scenes by adjusting the number of rectifier modules installed. The installation of power system is installed in the engine room on the ground floor, supporting the wall (away from the wall to be more than 100mm).
