20A PWM DC Motor Speed Controller - 12V/24V/36V/48V High Power Drive

This high-power PWM DC motor speed controller is a robust solution for driving brushed DC motors with precision and efficiency. Compatible with a wide input voltage range from 10V to 60V, it handles up to 20A of continuous current, making it suitable for heavy-duty applications like e-bikes, industrial machinery, and high-torque robotics. The module utilizes Pulse Width Modulation (PWM) technology to provide smooth, stepless speed adjustment from 0% to 100% via an onboard potentiometer. For enhanced safety and durability, it is equipped with a high-capacity aluminum heatsink, an inline fuse, and reverse polarity protection to safeguard against wiring errors. The compact metal-shell design ensures excellent heat dissipation and easy installation into any custom control panel.

Key Features:

• Universal Voltage Support: Works seamlessly with 12V, 24V, 36V, and 48V battery systems.
• 20A High-Current Drive: Delivers enough power for large motors up to 1200W peak.
• Smooth PWM Regulation: High-frequency switching ensures quiet and flicker-free speed control.
• Forward/Reverse Toggle: Built-in switch allows for easy directional changes without re-wiring.
• Advanced Safety: Integrated short-circuit, over-current, and thermal protection.
• Durable Aluminum Casing: Provides superior mechanical protection and cooling for internal components.
