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.
该公司位于俄罗斯，是一家电池制造商。主要从事俄罗斯工业电池和工业电池UPS生产和供应。客户应使用直流电表UPS监测和测量输出端电能。
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.
DJSF1352-RN导轨直流电能表主要设计在电信基站、直流充电桩、太阳能光伏等应用场合。该系列仪器可以测量直流系统中的电压、电流、功率和正反向电能。在实际使用现场，可以测量总电能和规定时间内的电能。测试结果不仅可用于本地显示，还可与工业控制设备和计算机连接，形成测控系统。
该仪器具有红外通信接口和RS-支持485通信接口，同时支持Modbus-RTU协议和DLT645-97(07)协议；可带继电器报警输出和开关量输入功能；通过仪表面板按钮，设置变比、报警和通信；有开关量事件记录（Modbus协议)、编程和事件设置记录(645协议)、数据瞬时和定时冻结功能(645协议)、电压电流功率峰值和谷值记录功能。
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.
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.
