Sourcing Isolation Transformers for BMS

In large battery pack applications with daisy chain connections, the high number of cells connected in series can generate greater voltage potential differences, which demand a higher level of component-to-component isolation. In these applications, serial communication links between boards need to be isolated by transformer coupling circuits instead of capacitor coupling.

BMS signal transformer is mainly used at the serial Daisy chain /IsoSPI interface of battery management system for pulse signal transmission, high voltage isolation and noise suppression. It is a single/dual channel isolation transformer module with 1000VDC~1600VDC working voltage and common mode choke for noise suppression.

The selection of a correct isolation transformer module is a choice of the module with the nearest, but higher, working voltage and the preferred number of channels, size and shape. Having a broad range of products, as offered by Jansum Electronics, makes the selection of isolation transformers more precise and simple.
