Features:
brand new high quality
Made of high quality material,
5V 12V 24V LED PWM DC Motor Speed Switching Regulator 5A 150W Dimmer Controller
Soft start function, when starting the motor, the current increases slowly, no surge current, effectively protecting the motor
Digital coding knob, high precision, good consistency, better than ordinary potentiometers, better than ordinary potentiometers
Adjustable duty cycle, duty cycle upper and lower limit, duty cycle minimum change value
With start and stop knob, can be controlled by external switch
Note: The motor will rotate when it is powered on by default
Product parameters:
Working voltage: DC 5-30V, input reverse polarity protection
Rated current: 5A, the maximum instantaneous current is 15A
Duty cycle: 0- , the default step value is 1%
Dimensions: 78.5mm x 43mm x 26mm / 3.09 x 1.69 x 1.02 inches
Encoder Knob Operating Instructions
1. In the default display interface (default display duty cycle) - Short press: switch on/off the motor - Long press for 10 seconds: enter the setting interface - Rotate counterclockwise: decrease duty cycle - Rotate clockwise: increase duty cycle
2. In the setting interface - Short press: select setting parameters: duty cycle upper limit, lower limit and step value - Duty cycle lower limit: If set to "L00-L80", the duty cycle will be between 0-80% - Duty cycle upper limit: If set to "H00-H99 or 100", the duty cycle will be between 0-100 - Step value (minimum change) selection: "A01, A02, A05, A10, A20, A25", that is, 1%, 2%, 5%, 10%, 20%, 25%, optional - Counterclockwise rotation: the corresponding parameter value decreases - clock rotation: the corresponding parameter value increases - Long press the knob to exit the setting interface
"STOP" port on the back of the board Can be connected to the switch button or 3.3V level, please do not use it in a complex electromagnetic environment, there is no protection inside the circuit (Note that the external switch should use a self-resetting button or key)
After all the setting parameters are running, the last setting will be automatically saved when the power is off
Package Included:
1 * DC motor speed controller
Note:
1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.
2.Please allow slight manual measurement deviation for the data.
