Product Description

*RS485 communication interface

*Supports Modbus-RTU protocol

*Relay alarm output and digital input function

*Set the ratio, alarm, and communication through the meter panel keys according to different requirements

*Event recording of switch (Modbus protocol), programming and event setting records, instantaneous and timing freeze function of data, maximum and minimum value recording function of voltage and current power

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.
