DC 12V 24V 36V 48V 12A 500W PWM Motor Speed Controller, Mini Speed Control Switch, Speed Regulator with Stepless Variable Rotary Knob – for Electric Motor, Brush Motor, Car, Generator, Fan (DC 9-60V)

This DC PWM motor speed controller is made of premium quality circuit board material, has a good and stable performance. Elegant and clear digital LCD HD display appearance, easy to read and set. Come with ON/OFF button, can be external switch control, to meet multiple control requirements (Note: The external switch should use the self-reset button or key, press to open and then press to close;it can’t realize the function of opening output when it is closed all the time, and closing output when it is not closed.) Soft-start function make sure the slowly current increasing, avoid the high shock current, effectively protect the motor and extend its service life Duty cycle can be set to adjust the motor speed. Duty cycle upper and lower limits can be set to meet your need. Frequency can be set to allow the motor work more stably. The setting parameters can automatically save to prevent data loss when power off. Adjustable digital encoder knob, more accurate and consistent than ordinary potentiometer. Standard 5135 instrument shell and input anti-reverse connection protection. Technical Specifications: Working voltage: DC 9V-60V Rated current: 12A Maximum current: 20A Maximum power: 500W Duty cycle: 0-100% Working frequency: 1KHz~99KHz, default frequency of 20KHz, accuracy of about 1% Size(L x W x H): 3.11″ x 1.69″ x 1.02″/ 79mm x 43mm x 26mm Applications: DC drive motor, generator, LED lights, light bulbs, lamp, car, fan, micro-pumps, solenoid valves, micro-pumps, solenoid valves; (note：for DC brushed motors, not for brushless motors) Package included: 1 x dc motor speed controller Net weight:1.5oz/42g Wide voltage range – DC 9-60V PWM motor speed controller switch, rated output current 12A, maximum output current 20A, max power 500W Settable duty cycle, duty cycle upper and lower limits and working frequency – set up these 3 parameters according your own motors; comes with start and stop button and can be controlled by external switch High percision digital encoder knob – can adjust the motor speed , more accurate and consistent than ordinary potentiometer, easy to match the value Soft-start protection – the current increases slowly when starting the motor, avoid the high shock current, effectively protect the motor and extend its service life Widely applications – good to control the output of power, brightness, speed; perfect for DC drive motor, generator, LED lights, light bulbs, lamp, car, fan, micro-pumps, solenoid valves, micro-pumps, solenoid valves; (Note: This product can only be used for DC brushed motors, not for brushless motors)
