高频开关模块电源是按照电力部订货条件DL/T459、及JB/T5777电力系统直流电源设备通用条件及要求。结合多年的直流系统的研制及制造经验而开发的无人值守电源系统。它综合了高频计算机，功率输出单元采用模块化(N+I)冗余设计，监控单元可采用高速PLC或微机，显示操作单元人机界面触摸屏，可带热插拔等优点。具有遥控、遥测、遥信、遥调功能，是新型的直流操作电源。适用于500KV及以下变电站、发电厂等无人值守场所。
The new generation H.F switcher free of watcher developed and produced according to DL/T459 order technical specification issued by Electric Power Ministry,JB/T5777 common technical specification of Electric power system D.C power supply devices and safety requirements，its achievement sources from many years experiences of D.C power supply’s development and manufacture．It combines H.V switching skills with computer ones，power units adopt modularized(N+1)redundant design，monitoring unit can use PLC controller and computer with high perfor-mance and high operating speed，display unit featured by modern touch screen with human—computer interface，its elements can be plug in and pulled out in energized condition of the device，we call it as“thermal operation”．It becomes modern．high quality D.C operating power supply because of its“Remote Control”，“Remote Measurement”，“Remote Communication”，“Remote Adjusting”excellent functions．It can be applied to operat—ing condition free of watchers in transformer sub-stations and generators with 500 KV capacity and the below．
