16S Battery Input

PMU 2 Lite supports 20V to 70V wide voltage input and is compatible with 16S batteries. It adapts to various power supply conditions and can easily meet the power needs of various unmanned systems in different scenarios, significantly improving its adaptability.

High-Performance Processor

PMU 2 Lite employs new STM32H5 Arm® Cortex®-M33 CPU with a frequency of 250MHz as the processor and the self-developed M4C architecture software. It adopts ITT3 temperature impedance tracking algorithm, enabling excellent measurement consistency in a wide temperature range and across the full measurement range. With an accuracy of ±0.05V / ±0.1A, it ensures the stability and reliability of data in complex environments.

Factory Pre-Calibrated

Each module is factory pre-calibrated and temperature-learned. The factory uses calibration architecture hardware to conduct load tests, temperature learning and pre-calibration across the full current and voltage ranges, ensuring that each module maintains excellent accuracy and stability under various working conditions. It is ready for immediate use without additional calibration.

15V/5V Output

PMU 2 Lite offers optional 15V or 5V output voltages, which are widely compatible with multiple controllers. It can meet various demands for power supply of devices and enable effective and convenient operation of device systems.
