12V Waterproof PWM Motor Speed Controller, Pulse Width Modulation Speed Regulator

This speed controller has a sophisticated and practical waterproof housing, so you can use it outdoors<br> <br> Comes with screw terminals and power pole indicator labels and motor controller for easy wiring<br> <br> The DC motor controller input terminal is connected to DC power, not AC power, otherwise it will turn off<br> <br> Make sure the positive and negative polarities are connected correctly, otherwise the controller will be damaged<br> <br> <br> Applicable current range: direct current within 10A<br> <br> Maximum current: 20 A<br> <br> Speed range: 5% to <br> <br> Potentiometer: resistor B100K;<br> <br> Hole 8mm;<br> <br> The output voltage is approximately 0- of the voltage 'input<br> <br> Control power: 12V*10A=120W, 24V*10A=240W<br> <br> Input voltage: DC10-60V<br> <br> PWM frequency: 25 kHz<br> <br> Size: 88 mm * 59 mm * 35 mm<br> <br> Precautions and instructions for use<br> <br> L. The input of the DC motor speed controller is direct current and it cannot be directly connected to alternating current (such as: household 220V AC, otherwise it will power off<br> <br> 2. The positive and negative poles of the DC power supply cannot be reversed, otherwise the regulator will be damaged.<br> <br> 3. The motor can be independently positive and negative, when the direction of travel is inconsistent with expectations. The direction can be changed by adjusting the line sequence<br> <br> 4. Adjusting the potentiometer knob can change the output duty cycle of the regulator, thereby changing the motor speed
