在电力行业中RTU[1]、DTU[2]、FTU[3]、TTU[4]等设备是配网自动化系统中的开关监控装置，适用于城市、农村、企业配电网的自动化工程，完成环网柜、柱上开关的监视和保护以及通信等自动化功能，配合配电子站、主站实现配电线路的正常监控和故障识别、隔离和非故障区段恢复供电，在电力行业有着广泛的应用。这些设备的内部设计上非常相似，其对电源的要求更是如此，下面以DTU为例介绍其供电电源解决方案。
DTU一般安装在常规的开闭所（站）、户外小型开闭所、环网柜、小型变电站、箱式变电站等处，完成对开关设备的位置信号、电压、电流、有功功率、无功功率、功率因数、电能量等数据的采集与计算，对开关进行分合闸操作，实现对馈线开关的故障识别、隔离和对非故障区间的恢复供电。部分DTU还具备保护和备用电源自动投入的功能。
DTU系统的工作原理
配电终端DTU的功能可以通过软件组态配置实现灵活组合，DTU功能模块实时监测压线路电压、线路电流、零序电流、设备状态等运行及故障信息，完成遥信、遥测、遥控功能，实现配网自动化的实时监控；保护功能实现线路故障就地检测、切除功能；通信管理模块具备多种方式的通信接口和多种标准通信规约，除具备终端内部数据管理功能，对外还可转发配电室或开闭站内电能表、PLC及直流屏数据，通过一个标准统一接口与主站系统通信完成数据传输等功能。配电终端采用集散式设计模式，强大的软、硬件组态配置功能既满足了DTU实时性要求，也实现了数据存储记录功能，同时又可实现线路微机保护独立配置功能，成功解决了测控、保护、通讯兼容共存问题，达到了简化站点设备种类的目的。
