{"product_id":"20a-dc-speed-motor-controller","title":"20A DC motor speed controller with PWM knob","description":"\u003cp\u003eThe 20A DC Motor Speed Controller is a high-current PWM module designed for precise speed control of DC motors, fans, pumps, and other heavy DC loads. With a simple rotary knob, you can adjust the output duty cycle from 0% to 100%, delivering smooth and efficient speed control without the power losses of resistive methods. The 20A rating makes it ideal for larger motors and higher-power applications where the 10A variant falls short.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePWM speed control via rotary potentiometer knob\u003c\/li\u003e\n\u003cli\u003eAdjustable duty cycle: 0% to 100%\u003c\/li\u003e\n\u003cli\u003eWide input voltage range: DC 6V to 30V\u003c\/li\u003e\n\u003cli\u003eMaximum continuous current: 20A\u003c\/li\u003e\n\u003cli\u003eHigh-efficiency MOSFET switching — minimal heat generation\u003c\/li\u003e\n\u003cli\u003ePWM frequency: ~13 kHz (inaudible range for most motors)\u003c\/li\u003e\n\u003cli\u003eLED power indicator\u003c\/li\u003e\n\u003cli\u003eCompact PCB with screw terminal connections\u003c\/li\u003e\n\u003cli\u003eSuitable for 12V and 24V DC systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInput voltage: DC 6V – 30V\u003c\/li\u003e\n\u003cli\u003eOutput current: 20A continuous (peak higher with heatsinking)\u003c\/li\u003e\n\u003cli\u003eControl method: PWM via potentiometer\u003c\/li\u003e\n\u003cli\u003eDuty cycle: 0% – 100%\u003c\/li\u003e\n\u003cli\u003ePWM frequency: ~13 kHz\u003c\/li\u003e\n\u003cli\u003eDimensions: ~50 x 40 mm (approx.)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-current DC motor speed control (12V \/ 24V)\u003c\/li\u003e\n\u003cli\u003eIndustrial fan and blower speed regulation\u003c\/li\u003e\n\u003cli\u003eWater pump and irrigation pump flow control\u003c\/li\u003e\n\u003cli\u003eHigh-power LED dimming\u003c\/li\u003e\n\u003cli\u003eDIY robotics, CNC, and automation projects\u003c\/li\u003e\n\u003cli\u003eSolar-powered DC load control\u003c\/li\u003e\n\u003cli\u003eElectric vehicle (EV) auxiliary motor control\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e For loads above 15A, attach an external heatsink to the MOSFET for reliable continuous operation.\u003c\/p\u003e","brand":"Embeded Studio | Pakistan's Leading Electronics Online Store","offers":[{"title":"Default Title","offer_id":61895638090098,"sku":"ES-DCMSC-20A-PWM","price":750.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/7935\/3202\/files\/20ADCMOTORSPEEDCONTROLLER.webp?v=1780414401","url":"https:\/\/embededstudio.com\/products\/20a-dc-speed-motor-controller","provider":"Embeded Studio","version":"1.0","type":"link"}
