Key benefits Precise, repeatable speed control: digital display shows motor rotation as a percentage (0–100%) for accurate adjustments. High-current capability: supports heavy loads with a maximum output current of 60A and a safe continuous current of 40A. Simple, reliable directional control: stepless speed knob plus a Forward–Brake–Reverse switch lets you change direction and stop quickly without complex wiring. Flexible input range: wide voltage support (10–55V) accommodates a broad set of DC power sources when matched to motor rated voltage. Main functions and specifications Input voltage: wide range 10–55V. Important: input voltage must equal the motor’s rated voltage. Output current: maximum 60A (peak), continuous 40A. Speed display: digital readout of motor rotation speed percentage 0–100% for exact speed setting and monitoring. Speed control: stepless knob for smooth acceleration and fine adjustments. Direction control: Forward–Brake–Reverse switch for straightforward directional changes. Motor type: designed to work only with brushed DC motors. Output control: adjusts output current to control motor speed precisely. Compatibility and installation notes Compatible with brushed DC motors only. Do not use with brushless motors. Ensure the input power supply voltage is the same as the motor’s rated voltage. Power supply capacity must be at least 1.5 times the rated power of the motor to ensure reliable operation and prevent voltage drop under load. Follow motor and power supply manufacturer wiring and safety recommendations during installation. Performance and practical considerations Use for applications requiring accurate speed percentage feedback and robust current handling. Continuous 40A rating supports extended operation under load; 60A peak handles short-term surges (motor startup or stalls). The stepless knob provides smooth speed ramps; the digital percentage makes it easy to reproduce settings. Typical use scenarios Small electric vehicles or go-karts using brushed DC traction motors where precise speed control and forward/reverse are required. Conveyor or feeder systems in light manufacturing that need adjustable speed and reliable current capacity for continuous runs. Robotics, automation, or DIY projects with brushed DC motors where repeatable speed settings and clear percentage feedback improve setup and tuning. Safety and best practices Confirm motor rated voltage and match the controller input voltage exactly before powering the system. Use a power supply with at least 1.5× the motor’s rated power to avoid brownouts and protect the controller and motor. Verify all connections, proper fusing, and thermal management according to your application and local electrical codes. This controller provides accurate, high-current speed control for brushed DC motors, with a clear digital display, stepless adjustment, and a simple forward/brake/reverse interface.
