Würth Elektronik Transformers for Battery Management Systems

Würth Elektronik WE-BMS Transformers are designed to fulfill the requirements in high voltage operation areas for a safe and reliable battery management system (BMS). These transformers feature a common-mode choke to filter noise and electrically isolate the signals, allowing them to support the BMS isolation and EMI noise suppression for a safe and reliable operation. WE-BMS transformers feature a low-profile design and a higher creepage distance that increases the safety and reliability of the system despite the footprint. Würth Elektronik WE-BMS transformers are suitable for solar energy storage, energy storage systems (ESS), and uninterrupted power supplies (UPS).
