??1.項目概述：

??Project Overview

??該公司位于加拿大，公司主要從事光伏這一行業(yè)?？蛻粝胍褂弥绷麟姳鞤JSF1352-RN和分流器，用于光伏系統(tǒng)電流電壓的監(jiān)測計量以及利用直流表的開關(guān)量功能進行控制。

??The company is located in Canada, and the company is mainly engaged in the photovoltaic industry. The customer wants to use the DC meter DJSF1352-RN and shunt to monitor and measure the current and voltage of the photovoltaic system and use the switch function of the DC meter for control.

??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(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。

??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.
