Description
Optimise the control of your DC motor with our 6V – 90V 15A PWM DC Motor Speed Regulator Controller. This advanced controller enables precise speed control through Pulse-Width-Modulation (PWM), offering a fully adjustable Duty Cycle from 0% to 100%. It provides a continuous current of 10A, ensuring efficient operation for your DC motor or other DC loads. Whether you’re working on a robotics project, cooling system, or industrial conveyor belt, this controller delivers reliable performance.
Built to last, the 6V – 90V 15A PWM DC Motor Speed Regulator Controller features a 20A fuse and includes comprehensive protection against reverse connection and over-voltage, safeguarding your equipment. The device is designed to handle an input supply voltage of DC 6V to 90V, with a maximum output power of 1000W, making it versatile for a wide range of applications. Its robust construction ensures it can withstand demanding conditions and the high PWM frequency of 16KHz guarantees smooth and efficient motor operation.
With adjustable duty cycles from 0% to 100%, you have full control over the motor speed, allowing for precise adjustments. The compact size (64 x 59 x 28mm) makes it easy to integrate into various setups without taking up much space. The controller also supports an external DC voltage control signal (0V – 5V), providing additional flexibility for your projects.

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:
- Remove potentiometer. (you may take it down from one side of the circuit board or potentiometer side down under your need);
- Connect 0V ~ 5V DC control signal to the middle pin marked 0V ~ 5V;
- 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
