Developed from XAP?s motorsport engineering heritage, the CMU-112 brings uncompromising precision and reliability to your battery system. It continuously monitors and balances 12 cells with ±1 mV accuracy, providing 3 kV galvanic isolation between the cell domain, logic, and CAN communication lines. Its modular architecture enables seamless scalability from 48 V to 800 V without hardware changes.
Using passive resistor balancing (?4.7 ? / 3 W) controlled by optocoupled MOSFETs, it ensures long-term cell health while maintaining voltage deviation below 25 mV. The onboard microcontroller manages measurement, balancing, communication, and diagnostics with integrated calibration memory and local fault logging.
With advanced protections against ESD, reverse polarity, and open-wire faults, the CMU-112 provides consistent operation even under harsh automotive or industrial environments.
Proven reliability from motorsport technology ? combining traceable precision, galvanic safety, and minimal maintenance for long-term, scalable battery systems.
