BMS Logic 12

Measuring module

Modular BMS for 24-1000V batteries

Logic 12 represents the second generation of measuring modules that takes the best from BMS Logic 2.0 and offers greater accuracy and energy efficiency. It determines voltage and temperature of the battery cells and does passive balancing of the cells on a command from the BMS controller.
