## Overview

The PWM DC Motor Speed Controller is a high-performance device designed for precise speed regulation of DC motors. With an input voltage range of 10-55V and a maximum current capacity of 60A, it features a user-friendly potentiometer for smooth adjustments, an LED display for accurate monitoring, and a robust aluminum enclosure for excellent heat dissipation. Ideal for various applications, this controller is a must-have for professionals seeking reliability and efficiency.

## Description

**Note: 1.DC motor governor, connected to DC power supply, not AC power;2.The rated voltage of the product is 10-55V, and the DC power supply is connected to the governor, which should be equal to the rated voltage, or the voltage is +-10%;3.The governor has a continuous output current of 40A and a maximum output current of 60A, which cannot be used continuously at the maximum current;4.If the load is too high, it is easy to cause the electrical components of the motor to burn;SpecificationsSize: 5.03 x 3.85 x 0.74 inch/ 128 x 98 x 19mmForward & Reverse: SupportSupply/load voltage: DC 10-55VMaximum current: 60AContinuous Current: 40APWM frequency: 15KHZSpeed Modulation Range: 0 ~ 100%Speed Control Type: Current modulation by potentiometer (with switch)Support Forward Reverse Rotation Control: By Forward-Brake-Reverse SwitchNote:The digital display is the percentage of motor full speed 0-100 actual speed of non-motorThe input voltage must be divided into positive and negativeThe input voltage should be equal to the rated voltage of the motor within DC 10-55V

## Features

- 【Regulate Range】 Input supply voltage: DC 10V-55V; Maximum current: 60A; Continuous current: 40A; Speed range: 0-100% ; Control frequency: 15KHZ.Please connect the DC power supply to use! Do not continue to use excessive load, the continuous current is 40A, and the peak value is 60A.
- 【Switch Function】The PWM DC motor speed controller come with switch function. High power speed controller switch which is much more adaptable and conveniently change the motor direction.
- 【Excellent Heat Dissipation Performance】 The enclosure of the speed controller for motor is an aluminum enclosure. Aluminum shell is very strong to prevent damage, holes on its side and top which are helpful for heat dissipation.
- 【Easy to Operate】The stepless motor controller has a simple potentiometer knob adjusts the motor speed from 0% ~ 100% smoothly. And with LED display is accurate to show 0 ~ 100% of the motor speed. The input voltage of PWM motor speed controller should be equal to the rated voltage of the motor within 10-55V,or it will be burnt.Do not reverse the positive and negative poles！
- 【Application】 The dc motor driver can be used to brush motor speed regulation, light dimming regulation in the DC circuit.Note: The motor cannot be used in electric vehicles.

## Questions & Answers

**Q: Will this work on a power wheel**
A: Works on our 24v Disney princess cinderella carriage by Dynacraft! I use a 40V Ryobi battery with this instead of the stock battery.

**Q: How can i get a schematics? Im looking to modify the knob to a trigger.**
A: The regulator comes with an install schematic which is duplicated on the back of the regulator itselfteses are the only docs that comes with the unit, you should try to contact the manufacturer for a better answer

**Q: Can you run two motors on this**
A: Yes if you bridge wires

**Q: Can you tell me ohms of the potentiometer please?  Need replacement.**
A: It's a 100K ohm potentiometer.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Used it for my trolling motor
*by A***N on November 17, 2024*

It worked great for dyi trolling motor control but the instructions aren't clear

### ⭐⭐⭐⭐⭐ Burned up immediately, but cheap so i got another....
*by T***. on March 29, 2023*

I got like 2 minutes of run time and it started clicking on and off. Unplugged and plugged in the battery and it just quit working. Took a closer look in the morning and noticed something burned out on the inside. It's pretty cheap and I already have the mounting figured out so I'll get another and see if this one works.....

### ⭐ Cheap, not reliable
*by S***N on July 26, 2023*

I tried to use this to convert a 12v powerwheels car to 18v run from my lithium-ion power tool batteries. I did a lot of careful research when planning the circuit and had all the recommended fuses, wire, etc. Unfortunately the PWM still failed. It worked well for about 3 days at 50% speed setting. I never turned it to full power during that time.I'm guessing, like other reviewers have said, that it's not actually rated for the claimed amperage.
