12V Motor Speed Controller, Waterproof PWM Motor Speed Controller Pulse Width Modulator

This speed controller has a sophisticated and practical waterproof housing, so you can use it outdoors Comes with screw terminals and power pole indicator labels and motor controller for easy wiring The DC motor controller input terminal is connected to DC power, not AC power, otherwise it will turn off Make sure the positive and negative polarities are connected correctly, otherwise the controller will be damaged Product description Applicable current range: direct current within 10A Maximum current: 20 A Speed range: 5% to 100% Potentiometer: resistor B100K; Hole 8mm; The output voltage is approximately 0-100% of the voltage 'input Control power: 12V*10A=120W, 24V*10A=240W Input voltage: DC10-60V PWM frequency: 25 kHz Size: 88 mm * 59 mm * 35 mm Precautions and instructions for use 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 2. The positive and negative poles of the DC power supply cannot be reversed, otherwise the regulator will be damaged. 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 4. Adjusting the potentiometer knob can change the output duty cycle of the regulator, thereby changing the motor speed
