摘要：本文介紹了安科瑞DJSF1352-RN直流電表在俄羅斯UPS計量系統(tǒng)中的應用。主要用于UPS系統(tǒng)中的輸出電能的計量，通過霍爾對電路系統(tǒng)進行計量、通訊和控制等。

??Abstract: This article introduces the application of “Acrel" DJSF1352-RN DC meter in the Russian UPS metering system. It is mainly used for the measurement of the output energy in the UPS system, and the measurement, communication and control of the circuit system through the Hall sensor.

??1.項目概述：Project Overview

??該公司位于俄羅斯，是一家電池生產(chǎn)公司延伸。主要在俄羅斯從事工業(yè)電池及UPS的生產(chǎn)和供應強大的功能嶋H需求？蛻粢褂弥绷麟姳恚糜赨PS輸出端電能的監(jiān)測計量優勢。

??The company is located in Russia and is a battery production company. Mainly engaged in the production and supply of industrial batteries and UPS in Russia. The customer needs to use a DC meter for monitoring and measuring the electrical energy at the output of the UPS.

??2.DJSF1352-RN介紹 DJSF1352-RN DC Energy Meters

??DJSF1352-RN導軌式直流電能表善謀新篇，主要針對電信基站、直流充電樁便利性、太陽能光伏等應用場合而設計方法，該系列儀表可測量直流系統(tǒng)中的電壓、電流信息化技術、功率以及正反向電能等發揮作用。在實際使用現(xiàn)場，即可計量總電能逐步顯現，又可計量規(guī)定時間段內的電能銘記囑托。檢測的結果既可用于本地顯示，又能與工控設備自動化裝置、計算機連接示範，組成測控系統(tǒng)。

??儀表可具有紅外通訊接口和RS-485通訊接口有很大提升空間，同時支持Modbus-RTU協(xié)議和DLT645-97(07)協(xié)議運行好；可帶繼電器警報輸出和開關量輸入功能；根據(jù)不同要求可能性更大，通過儀表面板按鍵部署安排，對變比、警報技術、通訊進行設置了解情況；具有開關量事件記錄（Modbus協(xié)議）、編程和事件設置記錄（645協(xié)議）技術研究、數(shù)據(jù)瞬時和定時凍結功能（645協(xié)議）、電壓電流功率峰值開展研究、谷值記錄功能姿勢。

??DJSF1352-RN rail-mounted DC power meter designed for telecommunications base stations, DC charging piles, solar photovoltaic and other applications, this series of meters can measure the voltage, current, power and forward and reverse energy and so on in the DC system.The actual use of the site, you can measure the total power, but also measure the energy within a specified period of time. The test results can be used for local display, but also with industrial control equipment, computers to form a measurement and control system.

??The meter can have infrared communication interface and RS-485 communication interface, and supports Modbus-RTU protocol and DLT645-97 (07) protocol at the same time.The meter can have relay alarm output and digital input function;You can set the ratio, alarm, and communication through the meter panel keys according to different requirements.The meter can have event recording of switch (Modbus protocol), programming and event setting records (645 protocol), instantaneous and timing freeze function of data (645 protocol), maximum and minimum value recording function of voltage and current power.

??3.型號及功能介紹 Type and Function Description

??Note：when dual DC input（D）function is selected，if Hall current sensor input is used in current channel, a power supply module shall be provided to supply power to the second Hall sensor; if D function is not provided, the built-in power supply of electric meter can be used.

??4.客戶要求 Customer Requirements

??客戶想計量UPS的實際輸出電能首要任務，來計算UPS儲能與耗能的轉化比綠色化，UPS輸入端用的是我們ADL系列的電表，輸出端用的是DJSF1352-RN直流電表發展，通過分流器采取電信號保持穩定，達到輸出端測量的目的。

??The customer wants to measure the actual output power of the UPS to calculate the conversion ratio of UPS energy storage to energy consumption. The UPS input end uses our ADL series electric meter, the output end uses DJSF1352-RN DC meter, and the electrical signal is taken through the shunt in order to achieve the purpose of output measurement.
