Overview
The MAD AMPX 120A HV ESC is a high-performance electronic speed controller (ESC) designed for 12-24S lithium battery systems. It supports a continuous current of 120A and features IPX4 protection, making it suitable for demanding UAV applications. The ESC is equipped with CAN communication, ensuring real-time data transmission and compatibility with flight controllers. With its synchronous freewheeling technology, it enhances throttle linearity, efficiency, and automatic energy recovery.
Key Features
- Dual throttle control: Supports CAN digital throttle and PWM analog throttle, prioritizing CAN throttle for precise control.
- Fast response time: Accelerates from start to full speed in just 0.60 seconds.
- Optimized for disc motors: Uses a specialized control algorithm for improved stability and performance.
- Automatic energy recovery: Enhances efficiency when reducing motor speed.
- Real-time communication: CAN interface enables seamless integration with flight controllers.
- Compact and easy to install: Conveniently placed screw holes for flexible mounting.
- Fully isolated control signals: Improves safety and reliability by separating control signals and power supply.
Protection Functions
- Short Circuit Protection: Automatically shuts down the output when a short circuit is detected, restoring operation after 100ms.
- Stall Protection: Resets throttle if a motor stall is detected and gradually restores normal operation.
- Voltage Protection: Issues an alarm if input voltage falls below 40V or exceeds 105V.
- Temperature Protection: Reduces output when ESC temperature exceeds 125°C, shutting down at 140°C and recovering at 80°C.
- Throttle Loss Protection: Cuts power if no throttle signal is received for more than 2 seconds, restoring it when the signal returns.
- Startup Protection: Prevents immediate motor shutdown if it fails to restart within 10 seconds.
