With a maximum current of 20A and a power range of 0.01-1000W, it features advanced PWM technology for smooth speed control. The LED display provides real-time voltage feedback, while the built-in safety fuse ensures reliable operation. Ideal for both hobbyists and professionals, this controller is your go-to solution for efficient motor management. ## Description A. The input of the DC motor speed regulator must be DC input, cannot be connected to AC input otherwise, the motor speed regulator will be burnt. B. The positive side and the negative side of DC power supply cannot be reversed connected, or the motor speed regulator will be damaged. C. Adjusting the potentiometer knob can change the duty ratio of the output of the motor speed regulator, and then change the speed of the motor. Note: This variable voltage and speed controller is for brushed dc motor, not suitable for brushless motor. Wide voltage Range: from DC 12V to 48V The maximum current can reach 20A ,suggest within10A for use. ## Features - input Voltage range: DC 12-48V (cannot be used in AC) - Current range: Rated current 10A (max. current 20A); Quiescent Current 0.005A (standby mode) - Power range: 0.01-1000W: PWM frequency: 16kHz - Fuse specification: 20A ceramic arc fast-melting fuse. - The maximum current can reach 20A ,suggest within10A for use.The following is the corresponding power of different voltages: 6V=60W, 12V=120W, 24V=240W, 36V=360W, 48V=480, 60V=600W, 72V=720W, 90V=900W. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07R52TZFJ | | Customer Reviews | 3.9 3.9 out of 5 stars (5) | | Date First Available | April 25, 2019 | | Item Weight | 14.5 ounces | | Manufacturer | tatoko | | Package Dimensions | 6.2 x 4.6 x 4.3 inches | ## Images ![DC Speed Controller, DC 12-48V 20A DC Motor Controller, Universal 0.01-1000W 16kHz PWM Stepless Brushed Motor Control, Variable Speed Control Generator Kit with Output Voltage LED Display - Image 1](https://m.media-amazon.com/images/I/51VLqThdf2L.jpg) ![DC Speed Controller, DC 12-48V 20A DC Motor Controller, Universal 0.01-1000W 16kHz PWM Stepless Brushed Motor Control, Variable Speed Control Generator Kit with Output Voltage LED Display - Image 2](https://m.media-amazon.com/images/I/41hgpT8ztPL.jpg) ![DC Speed Controller, DC 12-48V 20A DC Motor Controller, Universal 0.01-1000W 16kHz PWM Stepless Brushed Motor Control, Variable Speed Control Generator Kit with Output Voltage LED Display - Image 3](https://m.media-amazon.com/images/I/41oaYfMc0TL.jpg) ![DC Speed Controller, DC 12-48V 20A DC Motor Controller, Universal 0.01-1000W 16kHz PWM Stepless Brushed Motor Control, Variable Speed Control Generator Kit with Output Voltage LED Display - Image 4](https://m.media-amazon.com/images/I/31gJQSPI6RL.jpg) ![DC Speed Controller, DC 12-48V 20A DC Motor Controller, Universal 0.01-1000W 16kHz PWM Stepless Brushed Motor Control, Variable Speed Control Generator Kit with Output Voltage LED Display - Image 5](https://m.media-amazon.com/images/I/41bEned10RL.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.ec/products/148068736-dc-speed-controller-dc-12-48v-20a-dc-motor-controller](https://www.desertcart.ec/products/148068736-dc-speed-controller-dc-12-48v-20a-dc-motor-controller) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-11-14*
