1.項目概述：

Project Overview

該公司位于新加坡，是該國一家光伏系統(tǒng)安裝服務(wù)公司。主要使用了直流電表DJSF1352-RN和分流器，用于光伏系統(tǒng)電流電壓的監(jiān)測計量。

This company is located in Singapore and is the Photovoltaic system installation services company in Singapore. Mainly used DC energy meter DJSF1352-RN and shunt, used to measure and monitor current and voltage in PV system.

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(yīng)用場合而設(shè)計的，該系列儀表可測量直流系統(tǒng)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(shè)備、計算機連接，組成測控系統(tǒng)。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(xié)議；可帶繼電器報警輸出、開關(guān)量輸入/輸出。根據(jù)不同要求，通過儀表面板按鍵，對變比、通訊進行設(shè)置與控制。

產(chǎn)品符合 Q/GDW1825-2013《直流電能表技術(shù)規(guī)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(shù)規(guī)范》等標準的相關(guān)技術(shù)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.
