摘要
：本(běn)文(wén)介(jiè)紹了(liǎo)安科瑞(ruì)直流電(diàn)表DJSF1352在(zài)加(jiā)拿(ná)大(dà)光伏係統(tǒng)中(zhōng)的應用(yòng)。主(zhǔ)要(yào)用(yòng)於(yú)光(guāng)伏係統中的電(diàn)流的計量，配合(hé)分(fēn)流器(qì)對電流(liú)進行(háng)計量(liáng)。

Abstract: This article introduces the application of Acrel DC meters in  PV system in Canada.The device is measuring current,together with shunt.

1.項目概述
：

Project Overview

該(gāi)公司(sī)位(wèi)於加拿大(dà)，公司(sī)主要(yào)從事(shì)光伏這(zhè)一(yī)行業(yè)。客(kè)戶想要(yào)使(shǐ)用直流(liú)電表DJSF1352-RN和(hé)分流(liú)器，用(yòng)於光伏(fú)係統(tǒng)電流電(diàn)壓(yā)的(dí)監(jiān)測計(jì)量以(yǐ)及利(lì)用直流表的(dí)開(kāi)關(guān)量(liáng)功能進行控製。

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係(xì)列直流電能(néng)表(biǎo)的(dí)介紹(shào)

DJSF1352-RN Series DC Energy Meters

DJSF1352-RN係列直流電(diàn)能(néng)表是(shì)針(zhēn)對(duì)直流(liú)屏，太(tài)陽(yáng)能(néng)供(gōng)電，電信(xìn)基(jī)站，充電樁等應用(yòng)場合而設(shè)計(jì)的，該(gāi)係列儀(yí)表可(kě)測量直流(liú)係(xì)統(tǒng)中的(dí)電壓，電(diàn)流，功率，正向(xiàng)與反向電(diàn)能。既可用於(yú)本地(dì)顯(xiǎn)示(shì)，又能與(yǔ)工控設備，計(jì)算(suàn)機連接(jiē)，組成測控(kòng)係(xì)統。同(tóng)時它具(jù)有多種(zhǒng)外(wài)圍(wéi)接(jiē)口功能可(kě)供用(yòng)戶選擇
：帶有(yǒu)RS-485通訊接口，采(cǎi)用Modbus-RTU協(xié)議(yì)；可(kě)帶(dài)繼(jì)電(diàn)器(qì)報警輸出，開(kāi)關量輸入(rù)/輸出。根據(jù)不同(tóng)要求，通過(guò)儀表麵(miàn)板(bǎn)按鍵(jiàn)，對(duì)變比，通訊進行設(shè)置與(yǔ)控製。

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.
