Description
Elec& Eltek ( EEMPL) offer a wide range of transformers, including those for automotive battery management systems.
Automotive battery packs use daisy chain connections, for the extremely high number of cells used in each pack. Potential voltages differences require high component isolation strength. The serial communication from board-to-board requires an isolation transformer.
BMS Transformer Modules
- Provide hi-pot isolation up to 4300V
- Provide EMI suppression
- Support serial daisy chain isoSPI, SPI
- Operating temp.: -40°C to +125°C/+150 °C
- Compact size with 7.62 x 9.27 x 5.72mm
- AEC-Q200 for automotive application
