CUAV PMU 2 Lite Power Module 15V/5V, CAN Bus Power Management Unit, 220A, 20-70V Input

Overview

CUAV PMU 2 Lite is a power module (power management unit module) designed to measure system voltage and current in real time and provide regulated power output for compatible controllers via CAN bus communication.

Key Features

• Current detection: 0-220A, with overcurrent warning function
• Wide voltage input for 16S battery compatibility (supports 20V to 70V; 5V version label shows 12V-70V)
• Measurement accuracy: ±0.1A / ±0.05V
• Built-in STM32H5 Arm Cortex-M33 processor (250MHz); runs self-developed M4C architecture software
• Adopts ITT3 temperature impedance tracking algorithm
• Supports CAN bus communication protocol; compatible with ArduPilot and PX4 (as stated)
• Aluminum alloy shell with thermal design for improved heat dissipation
• Factory pre-calibrated and temperature-learned; ready to use without additional calibration
• Non-contact, coreless busbar current detection technology with CNC-machined current sensing sheets
• 15V / 5V output options (version dependent)
