　　2.DJSF1352-RN系列直流電能表的介紹

　　DJSF1352-RN Series DC Energy Meters

　　DJSF1352-RN系列直流電能表是針對直流屏、太陽能供電、電信基站、充電樁等應用場合而設計的，該系列儀表可測量直流系統中的電壓、電流、功率、正向與反向電能。既可用于本地顯示，又能與工控設備、計算機連接，組成測控系統。同時它具有多種外圍接口功能可供用戶選擇：帶有RS-485通訊接口，采用Modbus-RTU協議；可帶繼電器報警輸出、開關量輸入/輸出。根據不同要求，通過儀表面板按鍵，對變比、通訊進行設置與控制。

　　產品符合 Q/GDW1825-2013《直流電能表技術規范》、GB/T29318-2012《電動汽車非車載充電電能計量》、Q/GDW364-2009《單相智能電能表技術規范》等標準的相關技術要求。

　　DJSF1352-RN series intelligent DC energy meter is designed for applications such as DC panels, solar power,telecommunications base stations, and charging posts. This series of instruments can measure voltage, current, power,forward and reverse power in DC system. It can be used for local display, and connected with industrial control

　　equipment, computers, form a measurement and control system. And it has a variety of external excuse functions for the user to choose: RS485 communication interface, Modbus-RTU protocol, relay alarm output, digital input/output. According to different requirements, through the instrument panel keys, you can set the ratio, communication parameters.

　　The product meets the relevant technical requirements of the standard Q/GDW1825-2013 DC power meter specification，GB/T29318-2012 Non-vehicle charging electric energy metering for electric vehicles，Q/GDW364-2009 Single-phase energy meter

　　specification.
