GLFILL 5V 12V 24V Led Pwm Dc Motor Speed Switch Regulator 5A 150W Dimmer Controller

Features: brand new high quality Made of high quality material durable 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.
