1.項(xiàng)目概述：Project Overview

該公司位于俄羅斯，是一家電池生產(chǎn)公司。主要在俄羅斯從事工業(yè)電池及UPS的生產(chǎn)和供應(yīng)?？蛻粢褂?/span>直流電表，用于UPS輸出端電能的監(jiān)測計量。

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(dǎo)軌式直流電能表，主要針對電信基站、直流充電樁、太陽能光伏等應(yīng)用場合而設(shè)計，該系列儀表可測量直流系統(tǒng)中的電壓、電流、功率以及正反向電能等。在實(shí)際使用現(xiàn)場，即可計量總電能，又可計量規(guī)定時間段內(nèi)的電能。檢測的結(jié)果既可用于本地顯示，又能與工控設(shè)備、計算機(jī)連接，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，同時支持Modbus-RTU協(xié)議和DLT645-97(07)協(xié)議；可帶繼電器警報輸出和開關(guān)量輸入功能；根據(jù)不同要求，通過儀表面板按鍵，對變比、警報、通訊進(jìn)行設(shè)置；具有開關(guān)量事件記錄（Modbus協(xié)議）、編程和事件設(shè)置記錄（645協(xié)議）、數(shù)據(jù)瞬時和定時凍結(jié)功能（645協(xié)議）、電壓電流功率峰值、谷值記錄功能。

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.
