Crocodile HL50400 [50V, 600A]

Unleash Maximum Power with Crocodile HL50400 50V DC Motor Speed Controller – 400A Constant, 600A Peak

Searching for a robust, high-efficiency, and ultra-adaptable DC motor controller for your EV, industrial machinery, or robotics project? Our next-generation Crocodile HL50400 50V DC Motor Speed Controller is built to handle extreme loads while offering precision control across a broad range of applications.

Smart Control Meets Plug & Play Flexibility

This feature-rich controller supports a wide array of control methods for seamless integration into any system:

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

Whether you’re working on an EV conversion, autonomous robotics, or heavy-duty automation, this unit gives you total control.

Safe & Stable Operation with High Current Handling

Engineered for demanding use, the controller supports:

• Adjustable normal current limit: 0–400A
• Peak current capacity: 600A

With a built-in overcurrent limiter and thermal protection (shutdown at 70°C / 158°F), it protects both your motor and power supply, ensuring long-term durability and safe operation under all conditions.

Regenerative Braking & High-Frequency Operation

Enjoy energy recovery and smooth braking with 2-quadrant regenerative control, allowing you to decelerate efficiently and send power back to the battery. The high-speed 32-bit Cortex processor and 18kHz switching frequency provide responsive, noise-free performance even at high RPMs.

Key Features of the Crocodile HL50400 50V DC Motor Speed Controller :

• 4 control modes: hall throttle, joystick, direct PWM, RC PWM
• Fully configurable via TX/RX serial communication
• 2-quadrant regenerative drive
• 32-bit Cortex MCU for fast, reliable signal processing
• 18kHz high-frequency switching for quiet motor operation
• Adjustable acceleration ramp: 0–40s
• Universal 0–5V input (compatible with PLCs and analog devices)
• Duty cycle range: 0–100%
• Overheat protection: automatic shutdown at 70°C
• Heavy-load 15×5mm copper rails (400A continuous, 600A peak)
• Wide voltage input: 6–50V DC
• Dimensions: 300 × 100 × 43 mm | Weight: 1200g (without heatsink)
• Designed for optional external heatsink for max power

Built for Performance Under Pressure

While the board is lightweight and highly efficient, installing a heatsink is strongly recommended when operating at maximum output power. Proper thermal management guarantees consistent performance, protects your investment, and extends the controller’s lifespan.

The Crocodile HL50400 50V DC Motor Speed Controller Perfect for:

• Electric vehicle conversions
• Forklifts and industrial movers
• Motorized boats and watercraft
• Heavy-duty robotics
• Automation systems requiring high amperage

Upgrade your system with our professional-grade, intelligent Crocodile HL50400 50V DC Motor Speed Controller and take full command of your high-current motor setup — safely, efficiently, and with total flexibility.
