LED PWM DC Motor Speed Switch Regulator 5A 150W Dimmer Controller
Features
Soft-start function, When starting the motor, the current increases slowly, without inrush current, which effectively protects the motor
Digital encoder knob, High precision and better consistency, than normal potentiometer, Better than ordinary potentiometer
Adjustable duty cycle, duty cycle upper and lower limit, minimum change value of duty cycle
With start-stop knob, and can be controlled by an external switch
Note: the motor will turn on when power is on by default
Parameters
Operating voltage: DC 5-30V , input reverse polarity protection
Rated amperage: 5A , maximum instantaneous amps is 15A
Duty cycle: 0-100% , default step value 1%
Dimensions: 78.5mm x 43mm x 26mm / 3.09 x 1.69 x 1.02 inches
Encoder knob operation instructions
1. in default display interface (default is shows duty cycle)
- short-press: turn on/off motor
- long-press for 10 seconds: enter setting interface
- anticlockwise rotation: reduced duty cycle
- clockwise rotation: increased duty cycle
2. in setting interface
- short-press: choose setting parameters: duty cycle upper limits , lower limits and stepper value
- duty cycle lower limit: if set as "L00-L80", the duty cycle will be between 0-80%
- duty cycle upper limit: if set as "H00-H99 or 100", the duty cycle will be between 0-100
- stepper value(the minimum change) choose: "A01 , A02 , A05 , A10 , A20 , A25 ", which is 1% , 2% , 5% , 10% , 20% , 25% , optional
- anticlockwise rotation: the corresponding parameter value decreases
- clock rotation: the corresponding parameter value increases
- long-press knob to exit seeting interface
"STOP" port back of board
it can be connected switch button or 3.3V level , Do not use in complex electromagnetic environment, No protection inside the circuit
(Note that the external switch should use a self-return button or key)
After all setting parameters are running, the last setting is automatically stored after power off
Package Included:
1 * DC Motor speed controller
