Key Features

Stepless Smooth Speed Control: Infinitely adjust and control the operational speed of your DC motor with a smooth, responsive rotary dial. An excellent replacement choice for broken or failing factory switches, this stepless regulator features an extra-long panel knob screw designed to cleanly feed through thick project boxes, vehicle dashboards, or localized mounting panels.
Simple Color-Coded Wiring Setup: Get your DIY vehicle upgrades or workshop repairs running safely in minutes without technical confusion. Wire your component directly by connecting the red wire to the positive pole of your power supply and motor, the blue wire to the negative pole of the motor, and the black wire directly to the negative pole of the power supply.
Upgraded Internal Heat Dissipation: Engineered to directly combat thermal stress and premature failure during extended, continuous operation. This electronic fan heater speed controller is equipped with an integrated heavy-duty internal heat sink that ensures rapid, efficient heat dissipation to protect the board from overheating.
Safe 10A Low-Voltage Capacity: Universally compatible with a wide spectrum of 12V to 24V DC electric appliances and components. To completely prevent smoking, melting, or burned wires, the electronic circuitry is precision-calibrated to handle safe, stable low-to-moderate current flows under a strict 10A maximum threshold.
Multi-Scenario Automotive & DIY Fit: This budget-friendly 2-pack delivers exceptional value for vehicle owners, RV travelers, and workshop tinkerers alike. It is widely used to tune vehicle cab heaters, windshield defrosters, caravan ventilation fans, offset BBQ smoker blowers, train layouts, and small fluid pumps.
