## Overview

The HiLetgo 12V-40V 10A PWM DC Motor Speed Controller is a compact, high-performance module designed for precise speed regulation of DC motors. Featuring a wide input voltage range, continuous 8A output current with 10A peak protection, and built-in safeguards against short circuits and reverse polarity, it ensures reliable and safe operation. Ideal for Arduino enthusiasts and DIY professionals seeking efficient motor control with easy installation.

## Description

Important: This is DC motor controller, please make sure the input voltage is from DC power, do not use home 220V AC, otherwise it will burn out. 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 10%-100%. The motor speed controller can provide a continuous current of 8A to your DC motor or other DC load. Specification:100% brand new and high quality. Input supply voltage: DC 12V-40V The maximum output power: 400W The maximum continuous output current :8A The overload and short circuit protecting current is 10A Static Current:0.02 A ( Standby ) PWM frequency: 13kHz Duty Cycle adjustable: 10%-100% The operation environment temperature:-20℃-125℃(L*W*H): 6cm x 5.5cm x 2.8cm/2.36"x 2.16"x1.10"(approx)Net weight: 69g NOTE:This can NOT be used to the BRUSHLESS motor. Double check all connections before applying power and always turn off the power supply before making any wiring changes. Package Included：1*12V-40V 10A PWM DC Motor Speed Controller CVT Speed Switch Module

Review: It works - It works as expected. I guess this is either a 5 or 1 star item - LOL! This one is a 5 star.
Review: Nice - Work like it should.

## Features

- Using imported high-power FET, the load current up to 10A
- With fuse, to prevent short-circuit high current, causing burnout protection
- With reverse power protection, to prevent damage to the module when the power is reversed
- Original 63V / 1000uF large capacitor, to ensure the stability of the module
- Potentiometers are equipped with nuts, you can use without adding other components

## Questions & Answers

**Q: How much heat does this generate, as im putting it in a small plastic project box.**
A: As long as there’s a little room in the box you should be fine. There should be some air flow across the unit and you could always cut a couple of slits in behind where the potentiometer is sticking out. The aluminum heat syncs are ample size and the only thing I’ve noticed is radiant heat similar to other electronic devices enclosed. I’ve had no problems with two of these units and both are enclosed.  But err on the side of caution always, air flow holes / slits do wonders .
Hope this helped,

**Q: What is the 3-pin header on this board for? It's to the right of the fuse holder.**
A: The 3-pin header connects to the 3 pins of the potentiometer.  It looks like if you don't like the position of the knob, you can unsolder the pot, and use the header to run a cable to an external pot.

**Q: Write up states "allows controlling direction of a dc motor".  is this correct?  does it allow variable pwm current control of the motor ccw & cw?**
A: it will control the speed of a dc motor within the specified voltage range.  It will not reverse the direction of the motor

**Q: Is this a discrete controller or continuous?**
A: Question doesn't make sense.  PWM by definition is a continuous wave where the duty cycle can vary.   Almost all of these type devices pump out a square wave.   It can be 'rounded' some by putting a capacitor across the output (ie, a filter) - the final shape to be determined by current draw and capacitor size.   In hardware discrete is often 'digital.'    To some a square wave looks 'digital', but, PWM is not discrete and the wave is actually generated with analog electronics, not digital (in this device).    An Ardunio or other processor can generate PWM, and that would obviously be a digitally generated source.
