General
DJSF1352-RN Din-rail DC energy meter with dual DC input, mainly designed for telecom base stations, DC charging pile, solar photovoltaic and other applications, this series of meters can measure the voltage, current, power and positive and negative energy in the DC system. The test results can not only be used for local display, but also can be connected with industrial control equipment and computers to form a measurement and control system.
