## Overview

This PWM DC Motor Speed Controller is a compact, high-power module designed to regulate DC motor speeds across a wide voltage range (10-60V) with up to 20A current capacity. Featuring 0-100% pulse-width modulation at 25kHz, it ensures smooth and precise motor control. Lightweight and protected against static damage, it’s perfect for professionals seeking reliable, efficient motor management with heat dissipation considerations for continuous use.

## Description

Specifications: - Size: 7.5 x 4.2 x 2.8 cm. - Voltage: DC 10-60V. - Maximum power: 1200 W. - Max current: 20A (10A, less than 450W suggested, if continuous use, improve heat dissipation) -Flow adjustment range: 0-100% - PWM frequency: 25KHz. - Wire length: 20 cm. - Weight: 77 g. Package includes: 1 × Cruise control. Note: 1. Make sure the positive and negative polarity is connected correctly. 2. The wiring should not touch the heat sinks, or it will probably burn the circuit board. This is not a source module, it is necessary to connect to a DC motor for running

Review: Works as it should - Works good for throttling my external fuel pump in installed on obs suburban. The pump put out to much flow that I couldn turn down my external regulator enough because my return line was not big enough to handle the pump flow . Long story short put this in so’s I can slow pump speed down works great U can probably use it as a anti theft devise also if u needed to
Review: Great product but heat sensative. - The PWM worked very well until the dial was exposed to the high temperature of hot glue to hold it in place. I went through two of these before I realized how temperature sensitive they are. Just keep the hot glue and soldering iron away and all will be well.

## Features

- Regulating the DC motor speed with a wide range through pulse-width-modulatin
- Incorporating high power dc motor driver module
- Input voltage range from DC 10V to 60V, and output current 20A maximum(no more than 10amp, 450 watt if longtime working, and make sure the heat dissipation works well )
- Packed in an antistatic bag to protect it from static damage during transportation
- Well made and

### ⭐⭐⭐⭐⭐ Great product but heat sensative.

### ⭐⭐⭐⭐ Additional circuit protection may be needed
*by C***R on November 3, 2025*

This motor speed controller works as intended, but note that even though there is a dual diode MBR in the circuit it is only rated for 100V peak inverse voltage. This may not be enough for 24V+ applications, and a peak inverse voltage spike higher than 100V can kill the MOSFETs in this controller. You should add a flyback diode to the motor (see picture) with high reverse voltage protection (> 200V) and fast switching (< 100ns) to your motor's contacts. Do NOT use the slow switching 1N4007 because it will melt when the motor stalls during lower duty cycles. If the motor always runs at full speed when connected to this controller regardless of the potentiometer's position, most likely the resistance between drain and source (pins 2 and 3) on one or both of the MOSFETs has broken down due to a voltage spike. To test this, turn off all power to the controller and motor and check the continuity between drain/source (pins 2/3) on both MOSFETs with a multimeter. If there is continuity, the MOSFET is dead and the controller will not work.
