Unlock Maximum Power with the Crocodile HL200200 100V DC Motor Speed Controller – 350A Constant Current, Extreme Flexibility

Need a powerful, versatile, and high-efficiency solution for controlling large DC motors in EV conversions, forklifts, boats, or industrial machines? Our advanced DC Motor Controller delivers outstanding performance, safe operation, and ultimate reliability across a wide range of heavy-duty applications.

Intelligent and Flexible Motor Control

Designed for total flexibility, this controller supports four different input modes: potentiometer, hall throttle (0.8–4.2V), joystick control, direct PWM input (0–95%), and RC PWM receiver (1.5ms ±1ms). It also offers full serial communication via TX/RX for deep customization—ideal for custom EV projects, robotics, and industrial automation.

Massive Current Handling with Smart Protection

Equipped with intelligent current limiting, the Crocodile HL200200 100V DC Motor Speed Controller prevents overloads and ensures stable operation. You can easily set the continuous current limit from 0–350A, with a peak capacity of 500A. The controller also features overheat protection at 70°C (158°F), automatically safeguarding your system from thermal stress.

Ready for Heavy Loads – Heatsink Recommended

For maximum output power, it’s recommended to attach an external heatsink to the controller. Although it’s designed for ultra-high efficiency, adding cooling ensures optimal performance and extends the lifespan of your motor control system.

Regenerative Braking for Energy Recovery

Thanks to regenerative braking, you can recover valuable kinetic energy during deceleration, boosting the overall energy efficiency of your system—perfect for EV applications, boats, and heavy machinery.
