BMS Logic 18
Measuring module
Modular BMS for 24-1000V batteries
BMS Logic 18 extends the second generation of measuring modules and provides the means to measure parameters up to 18 cells. It determines voltage and temperature of the battery cells and does passive balancing of the cells on a command from the BMS controller.
- 6-18 cells
(accuracy ±4mV) - 18 temperature sensors
- Passive balancing (350 mA @4.2V)
- RS-485 (3500V RMS isolation)
