About this item

• Voltage regulator controller– with a self- fuse, it can automatically disconnect when the current is too large, and the fuse will automatically after cooling,dc motors
• Special attention: the pmm dc motor regulator module is connected to a dc power supply, and the power supply voltage does not exceed 12v, and it cannot be directly connected to a household 220v ac power, otherwise the module will be damaged,variable speed motor,pwm controller
• Variable speed controller– with fine workmanship, simple in design and very practical in use, easily win your favors,motor speed controller
• Speed controller for electric motor– rotate the potentiometer clockwise, the motor will ; rotate the potentiometer counter-clockwise, the motor will slow down,dc motor speed controller
• Pwm motor speed control– pulse width modulation with variable voltage input range has the advantage of making full use of the energy of the power supply, and the circuit is efficient,motor speed control
