General
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.
