Operating Instruction:
1. Connect it to the power, ensure the positive inversion switch located in the middle of the zero, and connected with a DC power supply(the DC supply voltage range is more than 6V and less than 30V). Warning: do not reverse the positive and negative terminals of DC power source, otherwise regulator may be damaged.
2. Connect it to the motor, the motor line can be positive or negative, when the running direction is not consistent with the expectative one, you can adjust the sequence of lines or switch position to change the direction.
3. Adjust the switch. Positive inversion switch is used to control the motor speed direction. When the switch is located on the zero position, the motor stops rotating.
4.Adjust the potentiometer knob. Adjusting potentiometer knob can change output duty ratio of the regulator, then motor speed change.

4. RioRand RR-PWM-15V Low Voltage Dc 1.8v 3v 5v 6v 12v 2a Motor Speed Controller PWM
Feature
Low Voltage DC 1.8V 3V 5V 6V 12V 2AMotor Speed Controller PWM
The maximum output power: 30W
Duty Cycle adjustable: 0%-100%
Description
DC Motor Speed Controller allows controlling the direction of a DC motor using a Pulse-Width-Modulated (PWM) DC voltage with a Duty Cycle fully adjustable from 0%-100%.
The motor speed controller is with a self-recovery fuse 2A and a Power-On LED light. It can easily provide a continuous current of 2A to your DC motor or other DC load.
Main technical parameters:
Input supply voltage: 1.8V-15VDC
The maximum output power: 30W
The maximum continuous output Current :2A
Duty Cycle adjustable: 0%-100%;
Specifications:
Item size: 32*32*15mm;
Package: 1 x motor speed controller ;
Operating instruction:
1. Connect your DC motor (or DC load) to the motor terminals as indicated on the wiring diagram.
2. Connect a voltage of 1.8V-15V DC to the circuit making sure of the correct polarity of the connection. Note that the voltage applied to the motor will be supply voltage applied to the circuit. It is recommended to add an appropriately rated fuse in line with the positive supply in order to protect the circuit from any possible short circuits.
3. You can now control the speed of the motor through potentiometer. Important Notes An appropriately rated fuse (rated a little higher than the maximum current you expect to draw) is recommended to ensure safe operation. The controller is safe with a self-recovery fuse 2A. It will be damaged if connect the supply voltage with wrong polarity. Double check all connections before applying power and always turn off the power supply before making any wiring changes
