1203B 3A PWM DC Motor Speed Controller Module

PWM DC Motor Speed Controller Speed Switch Module 6V/12V/24V/28V 3A 1203B

This DC Motor Speed Controller Module allows controlling the direction of a DC motor using a Pulse- Width-Modulated (PWM) DC voltage with a fully adjustable Duty Cycle from 0%-100%.

The 1203B motor speed controller can easily provide a continuous current of 3A to your DC motor or other DC load.

Operating instruction for DC Motor Speed Controller:

• Connect your DC motor (or DC load) to the motor terminals as indicated on the wiring diagram of DC Motor.
• Connect a voltage of 10V-36V 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 inline with the positive supply in order to protect the circuit from any possible short circuits.
• You can now control the speed of the motor through potentiometer.

Main technical parameters:

• Input supply voltage: 6V-28VDC
• Item size: 1.3*2*0.4 inches
• Net Weight:0.85 ounces
• Duty Cycle adjustable: 0%-100%,without switch.
• The maximum output power: 80W
• The maximum continuous output current: 3A

Operating instruction:

Before you attempt to wire the controller, make sure power is off.

WARNING: DO NOT REVERSE POSITIVE AND NEGATIVE POWER LOADS. THIS WILL DAMAGE THE CONTROLLER. 

TO CHANGE MOTOR DIRECTION, INTERCHANGE THE POSITIVE AND NEGATIVE WIRES OF MOTOR.

1. Connect wires refer to the “wiring diagram”.

2. Turn on the power, and adjust the potentiometer.

3. The LED indicates the power up and the speed of a motor.
