Description DC Motor Speed Controller PWM Control Start Stop Switch 12V 24V 36V 48V 30A Features Knob comes with start and stop function Slow start and slow stop time can be set Limit the upper and lower limit of the speed Frequency 1-100KHZ can be set Use digital encoder knob, stable and durable, high precision and better consistency Parameters can be set for power-down storage Product parameter Input voltage: DC6-60V (the specific voltage is equal to the rated voltage of the motor) Output voltage: linear under load Output current: 0-30A Continuous current: within 20A Speed regulation type: current regulation speed regulation method: encoder knob 360 degrees Speed adjustment range: 0-100% can be set Frequency: 1-100KHZ can be set Slow start and slow stop: Can be set Digital speed display: 0-100 percentage meter Wiring type: Barrier terminal block Support motor: brushed motor Module size: length * width * height 96mm*61mm*34mm Panel opening: length * width 92mm*56mm Installation method: embedded Package Includes: 1 x Speed Controller Digital encoder knob operation Short press-switch motor start and stop Long press-enter the setting interface Clockwise-increase Counterclockwise-Decrease Enter the setting interface short press: switch function 1 function 2 function 3 function 4 function 5 function 6 long press to save and exit Enter the setting interface to rotate: turn left to decrease the value, turn right to increase the value low start time setting Function 1: 000-100 The slow start to 100% speed time is adjustable between 0-10 seconds. The default is 1 second. Slow stop time setting Function 2: 000-100 The slow stop time is adjustable between 0-10 seconds. The default is 1 second. Speed lower limit setting function 3: 000-080 The minimum speed is adjustable between 0-80% and less than the maximum speed setting value. The default is 0. Speed limit setting function 4: 000-100 The maximum speed is adjustable between 0-100% and is greater than the minimum speed setting value. The default is 100%. Acceleration and deceleration value setting Function 5: 001 002 005 010 015 020 025 The speed changes correspondingly for each revolution 1%, 2%, 5%, 10%, 15%, 20%, 25%. Frequency setting function 6: adjustable between 1-100KHZ, default 15KHZ Notice: The input voltage must be divided into positive and negative, not 220V The input voltage should be equal to the rated voltage of the motor within 6-60V Such as the motor 12V input 12V, the motor 36V input 36V
