Product Description
This device consists of a component board and external MOS components. It operates by controlling the polarity of the voltage to engage the relay: positive voltage causes rotation to the right, while negative voltage causes rotation to the left. By adjusting the input voltage, the speed can be controlled: 1-4 volts for the first speed, 4-8 volts for the second speed, and 8-12 volts for the third speed. The system regulates high-power voltage, allowing the output voltage to vary between 230V and 380V, thereby adjusting the motor speed efficiently.
