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%


Item size: 32*32*15mm



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.
