Whether you’re building an electric vehicle, designing a robotic system, or managing an industrial automation project, our next-generation DC Motor Controller delivers the power, flexibility, and intelligence you need to achieve exceptional performance.
Multiple Input Modes for Total Control
Adapt to any application with our multi-mode input system:
- Standard potentiometer or hall throttle (0.8–4.2V)
- Joystick input
- Direct PWM signal (0–95%)
- RC PWM receiver input (1.5ms ±1ms)
- Full serial communication via TX/RX with customizable parameters
Crocodile FR50200 50V DC Motor Speed Controller fits seamlessly into everything from EV conversions to industrial tools and hobby electronics.
Intelligent Current Limiting & Safety Features
Protect your motors and power supply with the built-in smart current limiter:
- Adjustable continuous current: 0–200A
- Peak current: 300A
- Overheat protection at 70°C (158°F) to ensure safe operation and long system life
By regulating output, the controller prevents overloads, maximizing efficiency and durability under heavy-duty use.
Regenerative Braking & 4-Quadrant Operation
Benefit from energy recovery with regenerative braking in both directions. Thanks to its true 4-quadrant operation, this controller allows for drive or regeneration whether you’re going forward or in reverse – ideal for high-efficiency mobility systems.
