Overview
The MAD AMPX 300A HV ESC is a high-performance 5-14S lithium battery electronic speed controller (ESC) designed for demanding UAV applications. It delivers a continuous current of 300A with IPX4 protection for enhanced reliability. Featuring CAN communication, it enables real-time interaction with flight controllers. With dual throttle control (RPM + CAN) and firmware upgradability, it ensures superior performance and adaptability.
Key Features
- High Power Support: Operates on 5-14S LiPo (16V-64V) with a 300A continuous current rating.
- Ultra-Fast Response: Achieves full speed in just 0.28 seconds.
- Optimized for Disc Motors: Uses a specialized control algorithm for stability and efficiency.
- Synchronous Freewheeling Technology: Improves throttle linearity, efficiency, and energy recovery.
- CAN Communication: Real-time integration with flight control for status monitoring.
- Dual Throttle Control: Supports RPM signal & CAN digital throttle for precise control.
- Upgradeable Firmware: Ensures long-term adaptability through online updates.
- Overload Protection: Unlimited automatic restart capability.
- Compact & Easy Installation: Features pre-drilled mounting holes.
Protection Functions
- Short Circuit Protection: Automatically shuts down output; requires manual power cycle for recovery.
- Stall Protection: Resets throttle to zero and gradually restores normal operation.
- Voltage Protection: Alarms if voltage drops below 16V or exceeds 64V.
- Temperature Protection: Reduces output when above 125°C, shutting down at 140°C, and restoring at 80°C.
- Throttle Loss Protection: Cuts power if no throttle signal is received for 2+ seconds.
- Startup Protection: Prevents ESC shutdown if motor fails to start within 10 seconds.
