9-60V/12A/500W PWM Motor Fan DC Motor Speed Controller(With Shell)

1. Using two original high voltage and low resistance MOS tubes, as well as the front stage driver, better performance and more stable, support high voltage and high power2. Can set the duty cycle, duty cycle upper and lower limits and operating frequency, convenient for customers to operate according to their own motor operating characteristics3. Digital encoder knob to adjust the motor speed, than ordinary potentiometer adjustment, higher precision, better consistency, will not produce drift4. Motor soft start function, the current increases slowly when starting the motor, no impact current, effective protection of the motor, prolonging the life of the motor5. With start-stop button, and can be controlled by external switches, to meet a variety of customer control needs (note that the external switch should be a self-resetting button or key, press to turn on, and then press to turn off; can not realize the output has been closed to turn on the output is not closed to turn off the output of the function)6. With standard 5135 meter housing, and have a back cover, convenient for customer installation7. Motor start-stop indicator: start light on, stop light off8. Digital tube: display motor regulation duty cycle, duty cycle upper and lower limits and frequency9. Rotary encoder: left turn duty cycle decrease, right turn duty cycle increase, short press to control motor start/stop, long press to enter setting mode.10. Can be connected to the switching signal or 3.3V level signal control motor start-stop11. Operating voltage: DC9V ~ 60V, input anti-reverse connection protection12. Rated current: 12A Maximum current 20A13. Power: 500W14. Operating frequency: 1KHz-99KHz adjustable, 1KHz step, the default frequency of 20KHz15. Product size: 79mmx43mmx26mm16. Installation aperture size: 39.3mmx76.5mm17. Product weight: 43g
