OUHOE | PWM DC Motor Speed Controller Adjustable Knob Stable Output Low Heat for Car Fan Modification Industrial Equipment Use

Description:Multi-specification PWM DC motor speed controllers deliver stable, high-precision stepless speed regulation, suitable for DIY electronic projects, industrial equipment modification and small motor control scenarios.Features:1. High Precision PWM Adjustment: Adopts high-performance integrated circuit chip and high temperature resistant FR4 fiberglass circuit board, outputs stable pulse width modulation signal with less than 2% power loss, ensures smooth motor operation, improves speed control accuracy and effectively extends the service life of DC motors.2. Excellent Heat Dissipation Performance: High-power models are equipped with high thermal conductivity aluminum alloy heat sinks, quickly transfers and dissipates heat generated during high-load operation, supports long-term continuous working without overheating damage, greatly improves the working stability and durability of the module.3. Smooth Stepless Speed Control: Equipped with high-quality carbon film potentiometer and anti-slip adjustment knob (plastic/metal optional for different models), supports 0-100% stepless speed adjustment without jamming during operation, allows users to precisely adjust the motor speed to meet various usage needs.4. Anti-Interference Stable Operation: Built-in high-quality electrolytic filter capacitors, effectively filters input and output voltage ripples and suppresses electromagnetic interference, eliminates speed jitter during adjustment, ensures stable circuit operation and will not interfere with other connected electronic devices.5. Easy & Fast Installation: Adopts flame-retardant PVC wiring terminals with clear input and output marks, the wiring can be fixed firmly without falling off, no soldering is required during installation, even beginners can complete the wiring work quickly, effectively saving project development time.Specifications:Category: PWM DC Motor Speed Regulator ModuleMaterial: FR4 printed circuit board, integrated control chip, aluminum alloy heat sink (for high-power models), electrolytic filter capacitor, flame-retardant wiring terminal, plastic/metal adjustment knobSize: The smallest model is 3cm * 2cm, there are slight size differences between different specificationsColor: Circuit boards available in green, red, black, matched with blue/green wiring terminals, and multi-color adjustment knobsApplication: DIY electronic production, small DC motor speed control, industrial automation equipment modification, toy car speed adjustment, DC fan speed control, etc.Quantity: 6 optional specifications, sold per single moduleNote:1.
