Overview

The AMPX 40A (5-14S) Drone ESC w/heat sink is a high-performance electronic speed controller designed for UAV applications. It supports 5-14S LiPo batteries (16V-64V) and features CAN communication, dual throttle control (RPM+CAN), and multiple protection functions. The integrated heat sink ensures efficient thermal management, making it ideal for high-power drone applications.

Key Features

• Wide Voltage Compatibility: Supports 5-14S LiPo batteries (16V-64V).
• High Continuous Current: Provides 40A continuous current with 48A peak current limit.
• CAN Communication Interface: Enables real-time data exchange with flight controllers (voltage, current, temperature, and operation status).
• Firmware Upgradeable: Allows future software updates for improved performance.
• Overload Protection: Unlimited automatic restart for enhanced safety.
• IPX4 Protection: Ensures durability against water exposure.
• Throttle Calibration Support: Adjustable PWM input signal (50-500Hz) with 3.3V compatibility.

Protection Functions

• Short Circuit Protection: Automatically shuts down the output upon short-circuit detection and restarts after 100ms.
• Stall Protection: Resets throttle to zero upon motor stall.
• Voltage Protection: Prevents operation if voltage is below 16V or exceeds 64V.
• Temperature Protection: Reduces output at 125C, and shuts down at 140C. Resumes at 80C.
• Throttle Loss Protection: Cuts power if the throttle signal is lost for over 2 seconds.
• Startup Protection: Shuts down if the motor fails to start within 10 seconds.
