1. Overview

The DJSF1352-RN series of electric energy meters has dual DC inputs and is mainly designed for applications such as telecommunications base stations, DC charging stations, and solar photovoltaics. This series of instruments can measure voltage, current, power, and forward and reverse electrical energy in DC systems. In actual use, total electrical energy can be measured, and electrical energy within a specified time period can also be measured. The detection results can be used for local display and can also be connected to industrial control equipment and computers to form a measurement and control system. The instrument can have infrared communication interface and RS-485 communication interface, and support Modbus RTU protocol and DLT645-97 (07) protocol at the same time; Can be equipped with relay alarm output and switch input function; According to different requirements, set the transformation ratio, alarm, and communication through the dashboard buttons; Equipped with switch event recording (Modbus protocol), programming and event setting recording (645 protocol), data instantaneous and timed freezing function

Capable of recording (645 protocol), voltage, current, power values, and minimum values.

Application scope:

Suitable for DC metering of charging stations, battery, solar panel and other DC signal equipment for power measurement and energy metering. It can also be used for modern DC power supply and distribution systems in industrial and mining enterprises, civil buildings, building automation, etc.
