Features Adjustable Direction: The motor can be connected without any positive or negative direction. The direction can be changed by adjusting the line order. Wide Voltage Range: The adjustable voltage range of the DC motor governor is very wide, the ultra-wide range is 6V to 90V, which is more adaptable. Stable Performance: The motor adopts electronic control to adjust the working speed, and the performance is reliable and stable. The adjustment motor is smooth, no noise and no vibration, with power indicator, and the duty cycle adjustment range is wide. Flame Retardant Housing: The metal housing of the motor is highly flame retardant, making it safer to use. Standard aluminum housing protects internal circuits and components for long-term durability. Easy Installation: There are installation holes on the back cover of the motor, which is more convenient to install the motor. Designed to protect the controller board from damage and heat dissipation. Specification: Item Type: DC Motor Controller Material: Metal,electron component Input V1oltage: DC12V to 48V Rated Current: 20A Quiescent Current: 0.005A (standby state) Rated Power: 300W Voltage Regulation Range: PWM output range is 0% to 100%, the motor is adjusted to stop and run at the highest speed PWM Frequency: 25kHZ Motor Positive and Negative Direction: The motor can be connected regardless of positive and negative, and the direction can be changed by adjusting the line sequence Package List: 1 x Motor Controller Note: This type of governor is only used for brushed DC motors, not suitable for brushless DC motors, and cannot be used as a voltage regulator1. The input of the DC motor governor is direct current and cannot be directly connected to alternating current, otherwise it will burn out2. The positive and negative poles of the DC power supply cannot be reversed, otherwise the governor will be damaged3. The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the line sequence4. The potentiometer knob can change the output duty ratio of the governor, thereby changing the motor speed Package List 1 x Motor Controller
