Quantity:1 Pc x Motor Speed Controller. 
 
DC Controller is required in the following situations:
1. Need a wider speed range. 
2. Need fast dynamic response process. 
3. Automatic smooth transition is required during acceleration and deceleration. 
4. High torque is required when low speed operation is required. 
5. Good excavator characteristics are needed, which can automatically limit the overload current to the set current. 
6.And it is a DC Motor Speed Controller,Not a Voltage Controller. 
 
Note:
1. The power of the input power supply must be greater than 1.5 times the rated power of the motor to make the motor work (note: the input voltage and the rated voltage of the motor must be consistent). 
2. If there is a forward-reverse circuit regulator on the children's car, please be sure to connect the speed controller between the power supply and the forward -reverse circuit regulator of the children's car. Otherwise, the speed controller may be damaged.
