How Does A DJSF Series DC Energy Meter Work?

DJSF1352-RN has two channels dc circuits input. The input voltage shall not be higher than 120% of the rated input voltage of the product. 1A fuse shall be installed at the voltage input end. The current input should be external shunt or Hall current sensor. The instrument provides RS485 communication interface and supports Modbus-RTU protocol. Theoretically, up to 128 instruments can be connected on a line at the same time. Each instrument can set its Addr and baud, and also can be selected by setting.

DJSF Series DC Energy Meter FAQs



what is a DJSF DC energy meter?



DJSF dc energy meter with rs485is designed for DC screen, solar power supply, telecom base station, subway and other applications.

how does a DJSF DC energy meter work?



The DC voltage and the DC current are measured separately with two DMM, and the results are multiplied to get the DC power.
