PWM DC Motor Speed Regulator

PWM DC Motor Speed Regulator 3V  6V 12V 24V 35V Speed Control Switch Function 5A

DC motor governor input is DC, can not directly connected to the AC (for example: home 220V AC), otherwise it will burn!
DC power supply positive and negative terminals do not reverse, otherwise the governor may be damaged.
The motor can be positive or negative, when the direction of operation and expectations do not match, you can adjust the line order to change the direction.
Adjust the potentiometer knob to change the governor output duty cycle, the motor speed changes.

PWM DC Motor Speed Regulator 6V 12V 24V 28V 3A Speed Control Switch 1203B

This 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 can easily provide a continuous current of3A to your DC motor or other DC load.
Main technical parameters:
Input supply voltage:6V-28VDC
The maximum output power: 80W
The maximum continuous output current :3A
Duty Cycle adjustable:0%-100%


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 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.
3. You can now control the speed of the motor through potentiometer.
