Overload short circuit protection current 4A. Short-circuit automatic recovery time does not exceed 30s Pulse width modulation range: 5% - 100% This product is suitable for DC10V - 30V DC motor, fan, fish tank oxygen pump and other products. Precautions for use and instructions for use 1. DC motor governor input is DC10V - 30V DC / Cannot directly input AC [If home 80V - 250V is prohibited from direct use] 2. DC power input cannot be reversed, 3, the output motor is not divided into positive and negative. When the running direction and the expectation are inconsistent, the running direction can be changed by adjusting the line sequence or the forward/reverse switch. 4. Adjust the potentiometer knob to change the governor output duty cycle to change the motor speed to achieve the desired effect. Special reminder: This product is a 10V-30V DC motor governor. The maximum speed range cannot be greater than DC 30V 120W. Please use this product within the scope of use. This product is not suitable for dimming LED strips. ## Features - Adopt PWM speed regulation technology, with high conversion efficiency, stable circuit and performanceThe motor speed controller can easily provide a continuous current to your DC A good speed controller for DC motors.the speed of a DC motor with this controller. - Wide speed regulating range: DC 10-30V; Maximum output power is 120W (under the situation of more than 24V) - Maximum continuously output current: 3A; current of over-load short-circuit protection: 4A; short-circuit time: no more than 30s - Attached a potentionmeter for regulating the speed, a switch for controlling the forward or reverse direction and stopping DC motor - PWM pulse width adjustable range: 5%-95%; three LED indicator: Green LED indicates "Power On"; Red LEDs indicate forward or reverse direction ## Images ![PWM DC Motor Speed Controller 10V-30V 3A DC Motor Speed Controller, Reversible PWM Control Forward/Reverse Switch, DC Motor Pump Speed Adjustment - Image 1](https://m.media-amazon.com/images/I/61FGFpC3r+L.jpg) ![PWM DC Motor Speed Controller 10V-30V 3A DC Motor Speed Controller, Reversible PWM Control Forward/Reverse Switch, DC Motor Pump Speed Adjustment - Image 2](https://m.media-amazon.com/images/I/61H5PQJjQHL.jpg) ![PWM DC Motor Speed Controller 10V-30V 3A DC Motor Speed Controller, Reversible PWM Control Forward/Reverse Switch, DC Motor Pump Speed Adjustment - Image 3](https://m.media-amazon.com/images/I/51mAbPLwRML.jpg) ![PWM DC Motor Speed Controller 10V-30V 3A DC Motor Speed Controller, Reversible PWM Control Forward/Reverse Switch, DC Motor Pump Speed Adjustment - Image 4](https://m.media-amazon.com/images/I/81npxNuuy7L.jpg) ![PWM DC Motor Speed Controller 10V-30V 3A DC Motor Speed Controller, Reversible PWM Control Forward/Reverse Switch, DC Motor Pump Speed Adjustment - Image 5](https://m.media-amazon.com/images/I/81ZqlXdsipL.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.pl/products/75027406-pwm-dc-motor-speed-controller-10v-30v-3a-dc-motor](https://www.desertcart.pl/products/75027406-pwm-dc-motor-speed-controller-10v-30v-3a-dc-motor) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-14*
