This governor is used for DC brushed motors.2, not suitable for DC brushless motor speed; can not be used as a regulator or regulator!3. The motor can be divided into positive and negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the line sequence.★ Package includes: ★1 × DC governor 20A2×Quick connector★Special reminder: ★The DC motor governor is connected to the DC power supply.Never connect directly to home 110V AC.Otherwise the damage will be at your own risk! ## Features - ★ Product parameters: DC input voltage range 9V 12V 24V 48V 60V, output current 0-20A, power 1200W. - ★ Widely used: DC motor driver can be used for DC motor speed regulation and dimming. - ★ Speed control: Our motor control board can adjust the motor speed through potentiometers, and support clockwise/counterclockwise rotation adjustment. - ★ Note: Do not switch another direction when running at high speed. It can not be used on electric vehicles, nor on Unnet speed reducer motors. - ★ PWM: Pulse width modulation (PWM) with wide/variable speed has the advantage of making full use of the energy of the power supply, and the circuit is efficient. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Zhjsjs | | Item Weight | 5.9 ounces | | Package Dimensions | 5.98 x 4.09 x 1.54 inches | | Color | PWM 20A | | Batteries Included? | No | | Batteries Required? | No | ## Images ![Motor Speed Controller DC 9V 12V 18V 24V 36V 50V 60V 20A Pulse Width Modulation Regulator 1200W Stepless Variable Speed Forward and Reverse Switch Pulsed Reverse Switch Pulse - Image 1](https://m.media-amazon.com/images/I/51LBy0ItbDS.jpg) ![Motor Speed Controller DC 9V 12V 18V 24V 36V 50V 60V 20A Pulse Width Modulation Regulator 1200W Stepless Variable Speed Forward and Reverse Switch Pulsed Reverse Switch Pulse - Image 2](https://m.media-amazon.com/images/I/51s1XGnppaS.jpg) ![Motor Speed Controller DC 9V 12V 18V 24V 36V 50V 60V 20A Pulse Width Modulation Regulator 1200W Stepless Variable Speed Forward and Reverse Switch Pulsed Reverse Switch Pulse - Image 3](https://m.media-amazon.com/images/I/51bMTf98jDS.jpg) ![Motor Speed Controller DC 9V 12V 18V 24V 36V 50V 60V 20A Pulse Width Modulation Regulator 1200W Stepless Variable Speed Forward and Reverse Switch Pulsed Reverse Switch Pulse - Image 4](https://m.media-amazon.com/images/I/51G3nKnG-mL.jpg) ![Motor Speed Controller DC 9V 12V 18V 24V 36V 50V 60V 20A Pulse Width Modulation Regulator 1200W Stepless Variable Speed Forward and Reverse Switch Pulsed Reverse Switch Pulse - Image 5](https://m.media-amazon.com/images/I/51idoHJca7S.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.co.th/products/325397869-motor-speed-controller-dc-9v-12v-18v-24v-36v-50v](https://www.desertcart.co.th/products/325397869-motor-speed-controller-dc-9v-12v-18v-24v-36v-50v) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
