Isolation transformer

encapsulatedfor automotive applications

Isolation transformers with high withstand voltages are required for battery monitoring of lithium-ion batteries. The products in this series successfully combine a shift to high coupling (low leakage) with a shift to completely automatic winding by employing a new structure that makes automatic winding possible, resulting in isolation transformers that can provide stable performance characteristics. Even in terms of reliability, the separation of the connecting wire terminals for windings from the board connection terminals has yielded improvements in vibration resistance as well as highly-precise terminal flatness. Possible applications for these products include use not only for the monitoring of lithium-ion batteries installed in xEVs, but also the monitoring of lithium-ion batteries in HEMS, BEMS, FEMS, and other systems.
