By adjusting the duty cycle from 0% to 100% via the onboard potentiometer, you can smoothly vary motor speed, fan airflow, or LED brightness without the heat and energy waste of resistive voltage dividers. The wide 6V–28V input range and 3A\/80W capacity make it compatible with a broad range of DC motors and loads.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDC 6V – 28V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax Continuous Current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3A\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax Output Power\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e80W\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDuty Cycle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0% – 100% (fully adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eControl Method\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePotentiometer (onboard knob)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSwitch\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBuilt-in on\/off switch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e-40°C to +85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePackage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSMD construction\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3A 80W PWM\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOrigin\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMainland China\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eHow PWM Speed Control Works\u003c\/h3\u003e\n\u003cp\u003ePWM control rapidly switches the motor power on and off at a fixed frequency. By varying the ratio of on-time to off-time (duty cycle), the average voltage delivered to the motor changes — controlling speed without the energy loss of resistive methods. At 50% duty cycle, the motor receives approximately half voltage; at 100%, full voltage. This method is highly efficient and generates minimal heat in the controller.\u003c\/p\u003e\n\n\u003ch3\u003eWiring Guide\u003c\/h3\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnect power supply:\u003c\/strong\u003e Connect your DC power supply positive (+) to the controller’s VIN+ terminal and negative (−) to GND.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnect motor\/load:\u003c\/strong\u003e Connect the motor or load positive (+) to the controller’s OUT+ terminal and negative (−) to OUT−.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePower on:\u003c\/strong\u003e Toggle the built-in switch to ON.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjust speed:\u003c\/strong\u003e Turn the potentiometer knob clockwise to increase duty cycle (higher speed\/brightness), counter-clockwise to decrease.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFine-tune:\u003c\/strong\u003e For precise control, use a multimeter to measure output voltage while adjusting the potentiometer.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch3\u003eWhy Choose This PWM Controller?\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eWide voltage range 6V–28V\u003c\/strong\u003e — compatible with 6V, 12V, 24V DC systems\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eFull 0–100% duty cycle\u003c\/strong\u003e — complete speed range from stopped to full speed\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003e3A \/ 80W capacity\u003c\/strong\u003e — handles most small to medium DC motors and fan loads\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eBuilt-in on\/off switch\u003c\/strong\u003e — convenient power control without disconnecting wiring\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eHigh efficiency\u003c\/strong\u003e — PWM method wastes minimal energy as heat vs. resistive control\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eWide temperature range\u003c\/strong\u003e — -40°C to +85°C for industrial and outdoor applications\u003c\/li\u003e\n  \u003cli\u003e✅ \u003cstrong\u003eCompact SMD design\u003c\/strong\u003e — small footprint for integration into enclosures and projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCommon Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDC motor speed control (drills, pumps, conveyor motors)\u003c\/li\u003e\n  \u003cli\u003ePC and industrial fan speed regulation\u003c\/li\u003e\n  \u003cli\u003eLED strip and bulb dimming (DC LED loads)\u003c\/li\u003e\n  \u003cli\u003eArduino and Raspberry Pi motor control projects\u003c\/li\u003e\n  \u003cli\u003e3D printer heated bed power control\u003c\/li\u003e\n  \u003cli\u003eSolar charge controller load management\u003c\/li\u003e\n  \u003cli\u003eElectric bicycle and scooter throttle control\u003c\/li\u003e\n  \u003cli\u003eAquarium pump and aerator speed control\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this to control an AC motor?\u003c\/strong\u003e\u003cbr\u003eA: No. This controller is designed for DC loads only.
