Upgrade Your System with Our High-Performance Crocodile FRX40200 Motor Speed Controller

– 150A Constant Power, Ultra-Flexible Control

Looking for a powerful, versatile, and reliable solution to control DC motors in EV conversions, forklifts, robotics, or industrial machinery? Our intelligent DC Motor Controller delivers maximum efficiency, smooth control, and superior durability for demanding applications.

Intelligent Design for Ultimate Flexibility

This advanced controller supports multiple input modes, including potentiometer, hall throttle (0.8–4.2V), joystick, direct PWM (0–95%), RC PWM signal (1.5ms ±1ms), or full serial communication via TX/RX with deep parameter customization. Ideal for DIY projects, professional-grade robotics, and custom electric vehicles.

Real-Time Protection and Adaptive Cooling

With intelligent current limiting, adjustable from 0–150A (peak 200A), your motor and power system are fully protected from overload. Overheat protection kicks in above 70°C (158°F), ensuring safe, consistent operation. The built-in fan controller output adjusts cooling automatically to maintain peak performance.

Regenerative Braking & 4-Quadrant Operation

Enjoy energy-efficient control with 4-quadrant operation, including regenerative braking—recover energy during deceleration in both directions. Perfect for EVs, trolleys, and mobile systems where energy recovery is key.
