BMS Logic 12
Measuring module
Modular BMS for 24-1000V batteries
BMS 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.
- 4-12 cells
(accuracy ±3mV) - 12 temperature sensors
- Passive balancing (350 mA @4.2V)
- RS-485 (3500V RMS isolation)
