PWM DC Motor Speed Controller 12V–40V 10A

Control the speed of compatible brushed DC motors with this 12V–40V PWM Motor Speed Controller. It uses Pulse Width Modulation (PWM) technology to provide adjustable motor speed through a rotary control knob.

Designed for DC motor projects, DIY electronics, robotics, and other compatible applications, this compact controller offers an adjustable speed range and screw-terminal connections.

Key Features

• Wide DC Input Range: Designed for 12V–40V DC input.

• PWM Speed Control: Adjust the speed of compatible brushed DC motors.

• 8A Rated Continuous Current: Commonly specified continuous current for this controller version.

• 10A Maximum Current: Maximum current rating; not the recommended continuous operating current.

• 400W Maximum Output Power: Subject to input voltage, current, motor load, and cooling conditions.

• 13kHz PWM Frequency: Commonly specified PWM operating frequency.

• Adjustable Speed Range: 10%–100% duty-cycle adjustment.

• Screw Terminals: Convenient connections for the DC supply and motor.

• Compact Design: Suitable for compatible DIY and electronics projects.

Important Compatibility Notes

• This controller is designed for compatible brushed DC motors.

• It is not suitable for AC motors or brushless DC motors.

• Do not connect an AC power supply.

• Check the motor's voltage and current requirements before connecting it.

• Do not exceed the controller's rated continuous current or power limits.

• Correct input polarity is essential. Confirm the exact board's polarity and protection features before connecting power.

• Do not test the controller without a suitable connected load.

Safety and Installation

Use a DC power supply within the specified input voltage range. Check all connections before switching on the supply. Provide suitable ventilation and heat dissipation during operation. Disconnect power before changing wiring or servicing the circuit.
