X-BCU MASTER Controller
Please contact us for Sales.
In the X-Series BMS, the X-BCU provides total system monitoring and control, while the X-MCUP controllers manage battery cells directly. The X-BCU master controller supports connectivity for up to 20 X-MCUP controllers.
Originally developed for use in electric buses, the X-Series BMS’s patent pending expandable design is best suited for medium to high voltage lithium-ion battery packs and is highly configurable for many different applications. Features include isolated CAN bus communications, support for up to 240 cells, and automatic configuration of X-MCUP modules upon connection to the X-BCU master.
To learn more about this BMS master controller, see our X-Series overview or the X-BCU data sheet.
