This 6V–28V 3A PWM DC Motor Speed Controller allows you to smoothly regulate the speed of DC motors, fans, or adjust the brightness of LED strips using highly efficient Pulse Width Modulation (PWM). Featuring a dedicated aluminum heatsink for stable thermal performance, this module handles up to a 3A continuous current load. The integrated potentiometer knob includes a built-in switch function, allowing you to easily click the unit completely off to cut power.
6V–28V 3A PWM DC Motor Speed Controller Module with Switch Potentiometer
Overview
The 6V–28V 3A DC Motor Speed Controller utilizes Pulse Width Modulation (PWM) to provide smooth, variable speed control for brushed DC motors, miniature pumps, and cooling fans. It is equally effective as a low-voltage DC dimmer for single-color LED light strips. By cycling power efficiently rather than dropping voltage through resistive heat, this module minimizes power waste and significantly extends the lifespan of your electronic components.
Precision Control with Integrated Power Switch
The module is equipped with a smooth-turning rotary potentiometer paired with a premium, silver-finished control knob. Designed for sleek integration into custom instrument panels and project enclosures, the potentiometer features a built-in toggle click-switch. Rotating the dial completely counterclockwise delivers a tactile “click” that completely breaks the input power line, saving you the hassle of drilling and wiring a separate standalone power switch.
Robust Thermal Management & Stability
Engineered for reliable, continuous operation under load, this speed regulator features an onboard extruded aluminum heatsink directly mounted to the main power switching transistor. This ensures prompt heat dissipation even during long runtime sessions. The circuit is further stabilized by a trio of high-quality electrolytic filtering capacitors that suppress electrical ripple, isolate switching noise, and guard your inductive loads against sudden voltage surges.
