CAN PMU Power Management Unit
- 0.05V / 0.1A measurement accuracy.
- 5V/5A regulated output.
- Supports up to 62V voltage input and 110A current detection.
- Proprietary ITT algorithm.
Self-developed ITT algorithm empowers high-precision measurement
The CAN PMU employs a proprietary ITT impedance temperature tracking algorithm to compensate for measurement errors caused by impedance variations across different operating temperatures, ensuring consistent high-precision voltage and current measurements across a wide range of operating temperatures.
