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(duì)電信基站、直流充電樁、太陽(yáng)能光伏等應(yīng)用場(chǎng)合而設(shè)計(jì)，該系列儀表可測(cè)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(chǎng)，即可計(jì)量總電能，又可計(jì)量規(guī)定時(shí)間段內(nèi)的電能。檢測(cè)的結(jié)果既可用于本地顯示，又能與工控設(shè)備、計(jì)算機(jī)連接，組成測(cè)控系統(tǒng)。
??儀表可具有紅外通訊接口和RS-485通訊接口，同時(shí)支持Modbus-RTU協(xié)議和DLT645-97(07)協(xié)議；可帶繼電器警報(bào)輸出和開(kāi)關(guān)量輸入功能；根據(jù)不同要求，通過(guò)儀表面板按鍵，對(duì)變比、警報(bào)、通訊進(jìn)行設(shè)置；具有開(kāi)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(shí)和定時(shí)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.
3.型號(hào)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(jì)量UPS的實(shí)際輸出電能，來(lái)計(jì)算UPS儲(chǔ)能與耗能的轉(zhuǎn)化比，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，通過(guò)分流器采取電信號(hào)，達(dá)到輸出端測(cè)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.
