## Overview

The RioRand RR-PWM-15V is a compact, versatile DC motor speed controller supporting 1.8V to 15V input and delivering up to 30W power with a continuous 2A current. Featuring a fully adjustable PWM duty cycle from 0% to 100%, it offers precise speed control for DC brush motors. Its built-in power LED and self-recovery fuse enhance usability and safety, making it an essential tool for professionals seeking reliable, efficient motor management.

## Description

DC Motor Speed Controller allows controlling the direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0%-100%. The motor speed controller is with a self-recovery fuse 2A and a Power-On LED light. It can easily provide a continuous current of 2A to your DC motor or other DC load. Main technical parameters: Input supply voltage: 1.8V-15VDC The maximum output power: 30W The maximum continuous output Current :2A Duty Cycle adjustable: 0%-100%; Specifications: Item size: 32*32*15mm; Package: 1 x motor speed controller ; Operating instruction: 1. Connect your DC motor (or DC load) to the motor terminals as indicated on the wiring diagram. 2. Connect a voltage of 1.8V-15V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse in line with the positive supply in order to protect the circuit from any possible short circuits. 3. You can now control the speed of the motor through potentiometer. Important Notes： An appropriately rated fuse (rated a little higher than the maximum current you expect to draw) is recommended to ensure safe operation. The controller is safe with a self-recovery fuse 2A. It will be damaged if connect the supply voltage with wrong polarity. Double check all connections before applying power and always turn off the power supply before making any wiring changes

Review: Compact voltage controller that works well - The product did what it was supposed to do. The hookups are marked well and I like the compactness.
Review: DC motor controller - Ordered these to control 2 small brushless axial fans. Works great. Wide range of adjustment and screw terminals hold tight.

## Questions & Answers

**Q: Is the product here in the us? and not in china. couldn't cancel an order from china. it's going to take 45 days for the product**
A: For any product sold on Amazon:
The information you need is available right from the product page:
Look above the "add to cart" button, and read the estimated arrival date, and most especially, whether the item is "Fulfilled by Amazon", or "sold by and shipped from Amazon".  ALSO, underneath the bulletted description next to a product's photo, look for a link that says some number is "New from", or "News and Used from"; if you click it, a side menu slides out that shows sellers, prices, whether shipping is free or not, and the estimated delivery date.

**Q: Is this the best thing to dim some led lights ? Is it bad to use? I know it should work but...?**
A: I used 3 of these to control each color of a strip of SMD 5050 LEDs.  They work great.  No buzzing, smooth linear control.

**Q: what is the PWM frequency?**
A: Frequency can be changed with C2.
0.12nF	66.7KHz
1nF	       11.4KHz
10nF	1.2KHz
100nF	118Hz
1000nF	1.2Hz

**Q: Does the knob include an on/off function or does it just adjust the speed? Need to know if I need to purchase an additional power switch.**
A: The knob has an on/off function.

### ⭐⭐⭐⭐⭐ Compact voltage controller that works well
*by R***I on August 3, 2025*

### ⭐⭐⭐⭐⭐ DC motor controller
*by L***. on May 3, 2025*

Ordered these to control 2 small brushless axial fans. Works great. Wide range of adjustment and screw terminals hold tight.

### ⭐⭐⭐⭐⭐ Great for Pop Up trailer bunk fans!
*by C***Y on March 22, 2022*

I picked these up hoping I could get them to function in the bunk fans for our Pop Up trailer. They are actually a perfect fit and work great!. There is some wiring and drilling necessary to make these work. The job is easy if you know what you are getting into. I removed the resistor from the low speed switch and wired these in with the high speed switch. The knob on these have a click/off position which is perfect. I noted that although during the day you can't see it, at night you can see there is a red LED on the board which glows through the plastic housing of the bunk fan but it is not annoying at all. At low speeds these are perfect, and there is no motor whine.
