CAN PMU Power Management Unit
- 0.05V / 0.1A measurement accuracy.
- 5V/5A regulated output.
- Supports up to 62 V input voltage and 110 A current detection.
- Proprietary ITT algorithm.
CUAV independently develops ITT algorithms to assist high-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 high-precision voltage and current measurements at various operating temperatures.
