## Description

Specifications Product Size: 5.03 x 3.85 x 0.74 inch/ 128 x 98 x 19mm Forward & Reverse: Support Supply/load Voltage: DC 10-55V Maximum Current: 60A Continuous Current: 40A PWM Frequency: 15KHZ Speed Modulation Range: 0 ~ 100% Speed Control Type: Current modulation by potentiometer (with switch) Support Forward Reverse Rotation Control: Yes, by Forward-Brake-Reverse Switch Note: The digital display is the percentage of motor full speed 0-100 actual speed of non-motor The input voltage must be divided into positive and negative The input voltage should be equal to the rated voltage of the motor within DC 10-55V

Review: I was really impressed with this item! It came with connectors and a couple little extras. After about 10 mins of setup, not only did it look slick, but, it functions EXACTLY as described! Just what I needed for my highbanker pump! For anyone here doing the a similar project: - (x1) Harmnee Controller - (x1) Prospector's Dream Bac-Pac series highbanker. - (x1) 2,000 gph bilge pump - (x1) 12v 20ah Dakota Lithium battery - Misc. roll of 16ga wire. I've run it in the bath tub for over an hour, at all different speeds. Haven't had a single hiccup! Taking it to the woods in two days for real world testing but, I imagine everything will be great!
Review: These are so much cheaper than expected and works just like the expensive ones.

## Features

- ♕【Regulate Range】 Input supply voltage: DC 10V-55V; Maximum current: 60A; Continuous current: 40A; Speed range: 0-100% ; Control frequency: 15KHZ; Apply to: DC Brush Motor
- ♕【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.
- ♕【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: can this pulse 12v , would it be ble to pulse 12v injector for cleaning
?**
A: The voltage of your injector is between our controller voltage range (10~55V). If your injector is with a DC brush motor and the rated current is below the 60A, HARMNEE pwm motor speed controller will fit for your injector.  The rated current is equal to the rate of power divided by voltage 12V.

**Q: Why is there a 3 way switch for this?**
A: one is for turning off the motor and the other two are for forward and reverse.

**Q: Can it be used with arduino to control motor speed and direction?**
A: I can't imagine why not as long as the Arduino project meets the volt and amp capacities of the Controller.

**Q: Lemon? Two right most terminals wired to 20V battery but the voltage across the two left most terminals always 20V no matter the % of pot adjustment.**
A: unplug the pot and connect a meter to center leg and either side legs and check ohms clime as you turn the knob. Make sure all connections are correct. If pot works then controller is bad.

### ⭐⭐⭐⭐⭐ Review
*by E***G on 20 July 2025*

We have purchased three different DC controllers for this project. The first two were from China and rated at 30 amps. They both got very hot and failed at 10 amps. We subseuently purchased this controller, which was more sophisticated and had nice remote controls and a speed or percent power indicator. This one is rated at 40 amps, whereas our application required 12 amps, so we intended to run it at about 30% or rated output. At 12 amps, this one also got hot but didnot burn out. We reduced the running amperage to 10 amps and the device did not reach a failure temperature level. We will build this unit into our product but reduce the rating to maximum of 15 amps rather than the published 40 amps. The controls and indicator are very well done.
