​KEAcvise 12-Pack 1803BK/B PWM Motor Speed Controller - 1.8-12V DC Input, 2A Max Output with Adjustable Knob, for Model Cars/DIY Robotics/RC Toys/Educational Electronics Projects​

• Application This product is widely applicable to speed regulation of DC motors, fans, fish tank oxygen pump, and other DC 1.8V - 12V products.
• Motor Speed Controller It is an ultra - low - voltage DC motor speed controller with the chip model NE555, a potentiometer with switch function, and a 2A resettable fuse to protect the controller, along with a power - on indicator.
• High - performance The input power supply voltage is DC 1.8V - 12V. The maximum continuous output current is 2A, the maximum output power is 30W, and the duty cycle can be adjusted from 0% to 100%.
• Safety The speed controller is equipped with a self - restoring fuse. When the current is too high, the fuse will automatically disconnect. After cooling, the fuse will automatically restore.
• Precautions Please connect this DC controller to a DC power supply. Do not directly connect it to a household 220V AC power supply, otherwise it will be damaged. The power supply voltage should not be greater than 15V. This is a 2A high - current speed controller. It cannot drive a continuous current greater than 0.5A for continuous operation,such as for 775 motors. Please confirm again before purchasing.
