Feature:1. DECLINATION POSITION: The angle that the potentiometer deviates from the midpoint is the speed of the motor, the larger the declination angle, the faster the speed.2. JOYSTICK POTENTIOMETER: The speed controller is equipped with a joystick potentiometer to stop the governor at the midpoint.3. SIMPLE WIRING: The motor wiring can be divided into positive and negative poles, and the running direction can be changed by adjusting the wiring.4. PWM SPEED REGULATION: The motor speed regulator module adopts PWM speed regulation, which is less affected by noise and less interference.5. WIDE VOLTAGE RANGE: The input voltage of the motor speed controller is DC 1230V, suitable for 12V 50W and 24V 100W power.Specification:Item Type: Motor Speed ControllerProduct Material: PCBVoltage: DC 12-30VElectrical Rated Current: 3AMaximum Current: 6A (With Hall current detection chip, stop output when the instantaneous maximum value is greater than 6.4A)Speed Range: 0%-100%Applicable Power: 50W within 12V, 100W within 24V.Package List:1 x Motor Speed ControllerNote:Do not use it beyond the voltage range, otherwise it will break down the circuit board and cause irreversible damage.
