Description: Stepless speed switch motor drive module Connect it to the power, ensure the positive inversion switch located in the middle of the zero, and connected with a DC power supply(the DC supply voltage range is more than 6V and less than 90V). Warning: do not reverse the positive and negative terminals of DC power source, otherwise regulator may be damaged. Connect it to the motor, the motor line can be positive or negative, when the running direction is not consistent with the expectative one, you can adjust the sequence of lines or switch position to change the direction. Adjust the switch. Positive inversion switch is used to control the motor speed direction. When the switch is located on the zero position, the motor stops rotating. Adjust the potentiometer knob. Adjusting potentiometer knob can change output duty ratio of the regulator, then motor speed change. High efficiency, high torque, low heat generating Control the speed of a DC motor with this controller With reverse polarity protection, high current protection and potentiometer and reversible switch Specification: Material: Metal Product Name: 6/9-15A Input voltage: DC6V-90V Output voltage: linear under load Output current: 0-15A Continuous current: 10A Speed control type: flow adjustment Speed control mode: potentiometer (linear) Speed range: 0 - 100% Control frequency: 16KHZ Reverse polarity protection: there are triodes Overload protection: with fuse type Wiring type: fence terminal block Knob line length: 20cm / 7.87inch Module size: length x width x height 71 x 61 x 27mm / 2.8 x 2.40 x 1.06inch Product net weight: 76 grams Motherboard installation size: length x width 53 x 63mm / 2.09 x 2.48inch Potentiometer press to open the hole: 7mm / 0.28inch Package Includes: 1 Piece Motor Drive Module
