DJSF1352-RN rail-mounted DC power meter with double DC input channels, 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. In 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, and computers to form a measurement and control system.
The meter has an infrared communication interface and RS485 communication interface and supports Modbus-RTU protocol and DLT645-97(07) protocol at the same time. The meter has a relay alarm output and digital input function. It can set the ratio, alarm, and communication through the meter panel keys according to different requirements. The meter has event recording of the switch(Modbus protocol), programming and event setting records(645 protocol), instantaneous and timing freeze function of data(645 protocol), and maximum and minimum value recording function of voltage and current power.
