Practical Design: Ultra-low voltage dc motor governor; Potentiometer with switch function; Use a 2A resettable fuse to protect the controller; Power-on LED indicator.
Physical Parameters: input voltage range: DC 2.2-12 V, output voltage: 1.8-12 V adjustable (according to the power supply voltage), output current: <2A. Duty cycle adjustable 0%-100%.
Secure Enough: The speed controller is equipped with a self-recovery fuse. When the current is too large, the fuse is automatically disconnected. After cooling, the fuse is automatically restored.
Wide Applications: 4pcs PWM DC Motor Speed Controllers are suitable for the speed regulation of DC motor, fan, fish tank oxygen pump and other products in DC 1.8-12 V.
Special Attention: 1. Please connect this DC controller to DC power supply. Never connect directly to household 220V AC power supply, or it will be damaged. 2. Don't power supply larger than 12V. 3. This is a 2A high current governor, which can't drive larger than 0.5A continuous current / the 775 motor / children's car motor.
