Monitor string cell voltage, independent cells, battery bank current and temperature, and custom projects.
BDL-3927 is updated Battery Data Logger to meet IEEE measurement standards for battery voltage, string voltage, current and ambient temperature.
It is recommended by IEEE standards like IEEE 450, IEEE 1188 and IEEE 1106 to check battery voltage, current and temperature monthly or quarterly. It is also much more time saving to record these data during battery charge or discharge.
It is customized from 12V to 700V for different battery systems. And it has easy expansion for all battery systems. With wifi communication, you could easily view complete data and generate test report in the PC software.
