CAN PMU Power Management Module Brief:
The CAN PMU is a power management unit module designed for unmanned systems. It features an integrated STM32F4 processor running the CUAV ITT algorithm, enabling real-time, accurate measurement of system voltage and current. It supports input voltages of 6–62V and currents up to 110A, while providing a 5.4V/5A output (5A continuous; 8A peak for 120s) to power the controller. Utilizing CAN bus communication and supporting the standard DroneCAN protocol, each unit undergoes factory calibration to ensure consistent performance and high accuracy.
CAN PMU Power Management Module Feature:
- 0.05V 0.1A accuracy
- 5V / 5A regulated output
- Maximum support 62 V voltage input, 110 A current measurement

Digital communication safe and reliable
The CAN PMU uses the standard UAVCAN digital communication protocol, and all information is transmitted digitally, avoiding the errors caused by the traditional ADC being easily attenuated and interfered with.
Accurate power consumption estimate
Internally, it can be sampled in real time over 100Hz, and the power consumption/instantaneous power consumption can be calculated in real time. Accurate power consumption information can be transmitted to the flight control for safer and controllable flight missions.
Low EMl, 5A high current regulated output
Built-in voltage regulator with LT8645S chip, supports 62V input,5.4V/8A synchronous buck regulator, with ultra-low EMI and EMC, up to 95% conversion efficiency to meet the industry’s Unmanned Systems controller peripherals, and large application needs.
*Maximum instantaneous output current 8A.maximumcontinuous output current 5A
CUAV independently develops ITT algorithms to assist precision measurement
CAN PMU uses the self-developed ITT (impedance temperature track) algorithm to compensate for the measurement error caused by different operating temperature impedance changes, enabling CAN PMU to maintain consistent precision voltage and current measurements at various operating temperatures.
