DC Motor Speed Controller Board Module (PWM, 6-90V 15A)

Description

The DC Motor Speed Controller allows controlling direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0% ~ 100%. The motor speed controller can provide a continuous current of 10A to your DC motor or other DC load.

The circuit also includes a 20A fuse, with reverse connection of power supply and control voltage over-voltage protection function.

Specifications:

• Input supply voltage: DC 6V ~ 90V
• Maximum output power: 1000W
• Continuous output current: 10A
• Overload and short circuit protection current (Max current): 15A
• PWM frequency: 15KHz
• Duty Cycle adjustable: 0% ~ 100%
• Operating temperature: -20°C ~ 40°C
• Size: 64 x 59 x 28mm
• Includes a 20A fuse with reverse connection and over-voltage protection

Precautions:

• DC Motor Input – Connects to DC motors only (not suitable for AC).
• Motor Direction – Adjust wiring if motor rotation direction doesn’t match expectations.

Applications:

• Robotics – Control robot wheels, arms, or other motorized components.
• Fan Speed Control – Regulate fan speed in cooling systems.
• Conveyor Belts – Adjust conveyor belt speed in industrial setups.
• DIY Projects – Use it in custom motorized devices, hobby projects, and more.

Important Notes:

This can NOT be used to control the BRUSHLESS motor.

The speed regulator supports the use of an external DC voltage control (0V – 5V). Using the following steps:

1. Remove potentiometer. (you may take it down from one side of the circuit board or potentiometer side down under your need)
2. Connect 0V ~ 5V DC control signal to the middle pin marked 0V ~ 5V
3. Connect the earth wire of 0V ~ 5V DC control signal to the pin marked GND

Package Includes:

• 1 x 6V – 90V 15A PWM DC Motor Speed Regulator Controller
