Greenvora Charger
1 / 5
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 in the DC system. In actual site use, it can measure total power and energy within a specified period of time. Test results can be used for local display or integrated with industrial control equipment and computers to form a measurement and control system.
The meter features an infrared communication interface and RS485 communication interface, supporting Modbus-RTU and DLT645-97(07) protocols simultaneously. It includes relay alarm outputs and digital input functions. Users can set ratios, alarms, and communication parameters through the panel keys. The device also supports event recording, programming records, data freeze functions, and maximum/minimum value recording for voltage and current power.
