  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(néng)介紹(shào) 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(yào)求 Customer Requirements

  客(kè)戶(hù)想計量(liáng)UPS的實(shí)際輸出電能(néng)，來計(jì)算(suàn)UPS儲(chǔ)能與耗能的(dí)轉(zhuǎn)化(huà)比(bǐ)，UPS輸入端用的(dí)是(shì)我(wǒ)們ADL係列的(dí)電(diàn)表，輸出(chū)端用的(dí)是DJSF1352-RN直(zhí)流電表(biǎo)，通(tōng)過(guò)分(fēn)流器采(cǎi)取(qǔ)電信(xìn)號，達(dá)到輸出(chū)端測量(liáng)的(dí)目的(dí)
。

  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.
