Our advanced DC Motor Controller is engineered for flexible integration, smooth performance, and maximum safety, making it ideal for hobbyists and professionals alike.

Multi-Mode Control for Maximum Flexibility

The Crocodile FR10050 100V DC Motor Speed Controller supports a wide range of control methods, including:

• Standard potentiometer or hall throttle (0.8–4.2V)
• Joystick mode
• Direct PWM input (0–95%)
• RC PWM receiver signal (1.5ms ±1ms)
• Full serial communication via TX/RX for advanced parameter tuning

No matter your setup, this unit is ready to plug in and adapt with ultimate control precision.

Built-In Protection for Reliable Operation

Avoid overloads and prolong the life of your motor with the adjustable current limiter:

• 0–50A continuous
• Peak 70A surge handling

In addition, the controller is equipped with thermal protection, automatically shutting down at 70°C (158°F) to prevent heat damage and ensure safe, uninterrupted performance.

Note: For full power operation, a heatsink is recommended to enhance thermal dissipation and maintain peak efficiency under heavy load.

Regenerative Braking & 4-Quadrant Control

Enjoy energy recovery and dynamic handling with full 4-quadrant drive:

• Drive or regenerate in both forward and reverse
• Recover braking energy and send it back to your power source
• Perfect for electric vehicles and energy-conscious systems
