CAN PMU is a drone power management unit with a built-in STM32F4 processor and running the CUAV ITT algorithm. It can accurately measure the drone voltage and current in real time. It supports a maximum of 6-62V voltage and 110A current and can output 5.4V 5A. (Maximum instantaneous 8A / 120s, constant 5A) Powers the flight controller, uses CAN bus communication, supports standard UAV CAN protocol, and each PMU unit is factory calibrated to ensure good consistency and high accuracy.
Self-developed ITT algorithm to facilitate high-precision measurement
CAN PMU uses the self-developed ITT impedance temperature tracking algorithm to make up for measurement errors caused by impedance changes at different operating temperatures, enabling CAN PMU to maintain consistent high-precision voltage and current measurements at various operating temperatures.
Digital communication, safe and reliable
CAN PMU adopts standard UAVCAN digital communication protocol. All information is transmitted digitally to avoid error problems caused by traditional ADCs that are easily susceptible to attenuation and interference.
Accurate power consumption estimates
Internally through real-time sampling of more than 100HZ and real-time statistics of power consumption / instantaneous power consumption, pass accurate power consumption information to the flight controller to achieve a safer and controllable flight
Low EMI, 5A high current regulated output
Built-in voltage regulator uses LT8645S chip, supports 62V input, 5.4V / 5A * synchronous step-down voltage regulator, has ultra-low EMI and EMC, up to 95% conversion efficiency, meets the industry drone flight control peripherals, and power consumption Big application needs.
0.05V / 0.1A high-precision measurement
Good thermal performance
Thermal imaging tests at room temperature show that the 90A (24V) case temperature for only 3 hours of operation is only 78 degrees Celsius.
