ayetea DC Motor Speed Controller User Manual

1. Introduction

This manual provides comprehensive instructions for the installation, operation, and maintenance of the ayetea DC Motor Speed Controller. This device is designed to provide stepless speed regulation for various DC motors and electrical appliances operating on 12V or 24V DC power supplies.

Please read this manual thoroughly before using the product to ensure correct operation and to prevent damage.

2. Safety Information

• Always disconnect power before making any wiring connections or performing maintenance.
• This product is designed exclusively for 12V or 24V DC power supplies. Do not connect it to household 220V AC voltage, as this will cause severe damage and potential hazards.
• Ensure correct polarity during wiring. Reversing the positive and negative poles of the power supply can damage the controller and connected devices.
• Do not exceed the maximum rated current of 10A or the maximum power output of 120W (at 12V) or 240W (at 24V). Overloading can lead to overheating and device failure.
• This controller is generally suitable for brushed DC motors. It is not recommended for brushless motors or geared motors, as speed regulation may not be possible or could cause damage.
• Ensure adequate ventilation around the device, especially the heat sink, to prevent overheating during prolonged operation.

3. Product Features

• High Power Support: Handles up to 120W at 12V and 240W at 24V.
• Stepless Speed Regulation: Provides smooth, continuous adjustment of motor speed.
• Integrated Heat Sink: Features a heat sink for efficient thermal management and improved durability.
• Simple Wiring: Designed for straightforward installation and ease of use.
• Compact Design: Small form factor for versatile integration.

4. Installation and Wiring

Proper wiring is critical for the safe and effective operation of the speed controller. Refer to the diagram below for connection details.

Image 1: Wiring Diagram and Main Parameters

This image illustrates the wiring connections and key specifications of the speed controller. It shows the red wire for motor positive and power positive, the blue wire for motor negative, and the black wire for power negative. Also displayed are voltage, rated power, rated thermal current, and material.

Wiring Steps:

1. Red Wire: Connect the red wire to the positive (+) pole of your DC power supply and also to the positive (+) terminal of your DC motor.
2. Blue Wire: Connect the blue wire to the negative (-) terminal of your DC motor.
3. Black Wire: Connect the black wire to the negative (-) pole of your DC power supply.

Important Note:

• Ensure all connections are secure and insulated to prevent short circuits.
• Double-check polarity before applying power. Incorrect polarity can damage the unit.

5. Operating Instructions

Once the controller is correctly wired and power is supplied, you can begin operation:

Image 2: Speed Adjustment Knob

This image highlights the rotary knob used to adjust the motor speed. Rotating the knob clockwise increases speed, while counter-clockwise rotation decreases speed, with a distinct 'off' click at the minimum setting.

• Power On: Ensure your DC power supply is active.
• Adjust Speed: Rotate the knob on the controller clockwise to increase the motor speed. Rotate it counter-clockwise to decrease the speed. The knob provides a smooth, stepless adjustment.
• Power Off: Continue rotating the knob counter-clockwise until you feel a distinct 'click'. This will turn off the power to the motor.

6. Applications

The ayetea DC Motor Speed Controller is versatile and can be used in various 12V-24V DC electrical applications, including but not limited to:
