DJSF1352-RN-2 rail-mounted DC energy meter is designed mainly for DC charging piles, telecommunication base stations, solar photovoltaic and other application occasions. This series of instruments can measure voltage, current, power and positive and negative energy in the DC system. The test results can be used for local display and can also be connected with industrial control equipment and computers to form a measurement and control system.

Note:
1. When the negative current shunt is input, the option needs to be set to on in the instrument menu. See Section 6 Menu Programming Interface for details. If it is not set, the voltage value will be negative.
2.It is recommended to use 0.75mm2 or 1mm2 shielded twisted pair for the secondary weak signal line of voltage and current input, and the shielding layer needs to be connected to the ground.
