BMS Isolation Transformers & Common Mode Chokes

Pulse Electronics Isolation Transformers and Common Mode Chokes are a full line of solutions for battery management systems (BMS) for small to large battery pack systems. These BMS components serve serial port safety isolation and electromagnetic interference (EMI) noise rejection applications. These components are critical in large battery pack applications with daisy chain connections. With a high number of cells connected in series, large voltage differences demand component-to-component isolation. These BMS components have multiple package options available and can be customized for specific application requirements. Typical applications include electric vehicles, energy storage, marine, and aviation transportation.
