MAD AMPX 300A (5-14S) HV Drone ESC

Description

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 125C. shutting down at 140C. and restoring at 80C.
• 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.
