AEC-Q200 compliant signal transformer design includes basic electric insulation providing increased reliability/safety for high voltage EV and energy storage systems
RIVERSIDE, Calif., January 9, 2023 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today released the industry's first planar signal BMS transformer. Meeting the need for planar technology that can provide reliable and safe communication in a growing group of high voltage electric vehicle (EV) and other high energy storage systems, the U.S. patented Bourns® Model SM91806 Planar Signal BMS Transformer meets basic electric insulation requirements per IEC 60664-1, IEC 61558-1 and IEC 62368-1 standards.
Planar-style signal transformers have been introduced to increase design flexibility and robustness. They are also known to deliver cost efficiency and reliability advantages over conventional wire wound transformer designs due to their multilayer PCB isolation and full automation. Offering these benefits and more, Bourns' new planar signal BMS transformer features a working voltage up to 1000 VDC, superior clearance/creepage distance features and complies with Overvoltage Category II. It also provides a partial discharge level up to 1200 V for ESS usage.
The Bourns® Model SM91806 Planar Signal BMS Transformer is available now and is RoHS compliant*. For more detailed product information, please see: www.bourns.com/products/magnetic-products/transformers-planar.
*RoHS Directive 2015/863, Mar 31, 2015 and Annex.
