QWORK AC Motor Speed Controller (Model: QS35380) Instruction Manual

1. Introduction

This manual provides essential information for the safe and effective operation of your QWORK AC Motor Speed Controller, Model QS35380. This device is designed to efficiently manage the speed of AC motors and control the power supplied to various resistive and inductive loads by adjusting the output voltage.

Please read this manual thoroughly before installation and use, and retain it for future reference.

2. Safety Instructions

To prevent injury or damage to the device, always observe the following safety precautions:

• Ensure the input voltage is within the specified range of 110-120V AC.
• Do not exceed the maximum current rating of 15A. The device features an automatic power cutoff for overload protection.
• Connect a load to the output before attempting to regulate voltage. The output voltage display requires a connected load to show accurate readings.
• This device is intended for indoor use only.
• Keep the device away from water, moisture, and extreme temperatures.
• Do not attempt to open or modify the device. Refer all servicing to qualified personnel.
• Always unplug the device from the power source before making any connections or disconnections.
• Ensure the connected load's power consumption does not exceed 4000W for resistive loads or 1500W for inductive loads.

3. Product Overview

The QWORK AC Motor Speed Controller is designed for ease of use and reliability. Familiarize yourself with its components:

• ON/OFF Switch with Reset: Controls the main power to the unit. Includes a reset button for the overload protection.
• 15A Overload Protection: Automatically cuts power if the current exceeds 15A, protecting the device and connected equipment.
• Output Voltage Display: A digital display showing the current output voltage. Requires a connected load to function accurately.
• Rotary Control Knob: Used to precisely adjust the output voltage and, consequently, the speed of a motor or power to a load. Marked with percentage power.
• Input Power Cord: Connects the controller to a standard 110-120V AC power outlet (Type A/B plug compatible).
• Output Socket: A standard Type A/B socket for connecting your AC motor or other electrical load.

5. Setup

1. Unpack: Carefully remove the speed controller from its packaging. Inspect for any signs of damage.
2. Placement: Place the controller on a stable, dry surface, away from direct sunlight, heat sources, and moisture. Ensure adequate ventilation around the unit.
3. Connect Load: Ensure the device you wish to control (e.g., fan, motor, heater) is turned off. Plug the power cord of your device into the output socket of the QWORK AC Motor Speed Controller.
4. Connect to Power: Plug the QWORK AC Motor Speed Controller's input power cord into a standard 110-120V AC wall outlet.

Important: Always connect the load first before plugging the controller into the wall outlet. The output voltage display will only show a reading when a load is connected.

6. Operating Instructions

1. Power On: Flip the ON/OFF switch to the "ON" position. The output voltage display may illuminate.
2. Adjust Voltage/Speed: Slowly rotate the control knob clockwise to increase the output voltage and power to the connected device. Rotate counter-clockwise to decrease. The digital display will show the approximate output voltage.
3. Monitor Performance: Observe the performance of your connected device. Adjust the knob until the desired speed or power level is achieved.
4. Power Off: To turn off the connected device, either rotate the control knob fully counter-clockwise to the "0" position or flip the ON/OFF switch to the "OFF" position. For complete power disconnection, unplug the controller from the wall outlet.

7. Maintenance

• Cleaning: Disconnect the controller from the power outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Storage: When not in use, store the controller in a cool, dry place, away from direct sunlight and extreme temperatures.
• Inspection: Periodically inspect the power cord and housing for any signs of damage. If damage is found, discontinue use and contact customer support.
