It features PWM adjustment for precise motor speed control and is compatible with various voltage systems (12V, 24V, 48V). Safety is prioritized with a recommended fuse, ensuring reliable operation for all your creative projects. ## Description Description: The PWM is an adjustable way of changing the voltage of the two ends of the load through controlling the DC power switching frequency of the steady voltage to meet the demand of controlling some certain voltage, which has extensive use, such as, motor speed regulation, temperature controlling, pressure controlling and so on Features： Power requirement:10-50V DC Rated current: 40A Max. Frequency : 12000Hz Control Motor Power : 0.01-2000W, 12V:480W(max),24V:960W(max) 36V:1440W(max),50V:2000W(max) Regulation range:5-100% PCB Size:90x51mm(inch:3.5 quot;x2 quot;) Case size:105x55x40mm(inch:4 quot;x2.2 quot;x1.6 quot;) The operation environment temperature: -20 degrees to 40 degrees Specification: Package weight: 130g Color: the outside cover is black, and the inside combines the green and white PCB Size: 90x51mm (inch: 3.5 quot;x2 quot;) Case size: 105x55x40mm (inch: 4 quot;x2.2 quot;x1.6 quot;) How to use: Connect your motor (or DC load) to the motor terminals as indicated on the writing diagram. Connect a voltage of 10 to 50V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the circuit. It is recommended to add an appropriately rated fuse inline with the positive supply in order to protect the circuit from any possible short circuits.You can now control the speed of the motor through potentiometer. -------------------------------------------------------- Package Including 1 x 10-50V 40A DC Motor Speed Control PWM HHO RC Controller 1 x User manual ## Features - PWM adjustment 2000W,40A max. - An appropriately rated fuse ( rated a litter higher than the maximum current you expect to draw) is recommended to ensure safe operation, - The controller is not reverse-polarity protected and will be damage 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 writing changes, - Changing the orientation through adjusting the order of the cable, - Change the occupying vacancy proportion of governor output by adjusting the regulating knob of potentiometer, and the revolving speed of electric machine will change ## Images ![Makerfire DC Motor Speed Control PWM HHO RC Controller 12V 24V 48V 2000W MAX 40A DIY Wiki - Image 1](https://m.media-amazon.com/images/I/71pRjDdNaQL.jpg) ![Makerfire DC Motor Speed Control PWM HHO RC Controller 12V 24V 48V 2000W MAX 40A DIY Wiki - Image 2](https://m.media-amazon.com/images/I/61Zb6x4C+xL.jpg) ![Makerfire DC Motor Speed Control PWM HHO RC Controller 12V 24V 48V 2000W MAX 40A DIY Wiki - Image 3](https://m.media-amazon.com/images/I/61UNMO++-wL.jpg) ![Makerfire DC Motor Speed Control PWM HHO RC Controller 12V 24V 48V 2000W MAX 40A DIY Wiki - Image 4](https://m.media-amazon.com/images/I/51ecsujhVML.jpg) ![Makerfire DC Motor Speed Control PWM HHO RC Controller 12V 24V 48V 2000W MAX 40A DIY Wiki - Image 5](https://m.media-amazon.com/images/I/61xxXZCpa2L.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/9338171-makerfire-dc-motor-speed-control-pwm-hho-rc-controller-12v](https://www.desertcart.sc/products/9338171-makerfire-dc-motor-speed-control-pwm-hho-rc-controller-12v) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-05-09*
