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.项目概述：Project Overview

该公司位于俄罗斯，是一家电池生产公司。主要在俄罗斯从事工业电池及UPS的生产和供应。客户要使用直流电表，用于UPS输出端电能的监测计量。

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介绍 DJSF1352-RN DC Energy Meters

DJSF1352-RN导轨式直流电能表，主要针对电信基站、直流充电桩、太阳能光伏等应用场合而设计，该系列仪表可测量直流系统中的电压、电流、功率以及正反向电能等。在实际使用现场，即可计量总电能，又可计量规定时间段内的电能。检测的结果既可用于本地显示，又能与工控设备、计算机连接，组成测控系统。

仪表可具有红外通讯接口和RS-485通讯接口，同时支持Modbus-RTU协议和DLT645-97(07)协议；可带继电器警报输出和开关量输入功能；根据不同要求，通过仪表面板按键，对变比、警报、通讯进行设置；具有开关量事件记录（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、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.

3.型号及功能介绍 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.客户要求 Customer Requirements

客户想计量UPS的实际输出电能，来计算UPS储能与耗能的转化比，UPS输入端用的是我们ADL系列的电表，输出端用的是DJSF1352-RN直流电表，通过分流器采取电信号，达到输出端测量的目的。

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.
