2. Features
- Accurate Voltage Regulation: Unique circuit design ensures precise voltage control without hysteresis. Adjusts from 10V after turn-on to near input voltage for resistive loads.
- Enhanced Protection: Incorporates an RC absorption circuit for thyristor protection.
- Efficient Cooling: Features an upgraded fan with intelligent switch control for effective heat dissipation and extended service life.
- Durable Construction: Housed in a standard high-grade aluminum shell for safety and practicality.
- High Current Capacity: Equipped with brand full copper 75A ultra-high current binding posts.
3. Safety Information
WARNING: Improper use of this device can result in electric shock, fire, or damage to equipment. Always follow these safety guidelines:
- Ensure the load connected does not exceed the specified maximum power of 10000W (for resistive loads).
- For inductive or capacitive loads, which have a large starting current (2-4 times the usual operating current), the power should be significantly reduced during use. It is recommended to leave at least half of the margin for such loads.
- Monitor the temperature rise during initial use. If the temperature exceeds 80 degrees Celsius, strengthen heat dissipation immediately to prevent damage to the module and connected appliances.
- All electrical connections should be made by a qualified professional and comply with local electrical codes.
- Do not operate the device in wet or damp conditions.
- Ensure proper ventilation around the unit.

5. Setup Instructions
Follow these steps to properly connect your voltage regulator:
- Power Off: Ensure the main power supply to the circuit is turned off before making any connections.
- Identify Terminals: Locate the "AC Input" and "Voltage Output" terminals on the regulator.
- Connect Input: Connect the AC power source (110V-230V) to the "AC Input" terminals. Ensure correct polarity if applicable, though for AC, typically live and neutral can be interchanged unless specified.
- Connect Output: Connect the electrical circuit of the consumer device (e.g., electric furnace, water heater, lamp, motor) to the "Voltage Output" terminals.
- Wiring Note: The regulator should be connected in series with the live wire of the electrical circuit. It is not necessary to connect the neutral wire through the regulator.
- Secure Connections: Ensure all wire connections are tight and secure to prevent arcing or overheating.

6. Operating Instructions
Once the regulator is correctly installed and connected, follow these steps for operation:
- Power On: Restore power to the circuit.
- Adjust Voltage: Rotate the potentiometer knob on the regulator to adjust the output voltage.
- Turning the knob will vary the voltage supplied to the connected device.
- This adjustment can be used for dimming lights, controlling motor speed, or regulating temperature in heating elements.
- Monitor Performance: Observe the connected device's behavior and ensure it operates within its safe limits.
- Heat Management: Continuously monitor the regulator's temperature, especially during high-power operation. If the unit becomes excessively hot, reduce the load or improve ventilation.

Application Examples
This voltage regulator is suitable for a wide range of applications, including:
- Electric furnaces and water heaters
- Lamps and lighting systems (dimming)
- Large motors and power tools (speed control)
Note: For inductive or capacitive loads, ensure the operating power is significantly below the 10000W maximum to account for high starting currents.

7. Maintenance
To ensure optimal performance and longevity of your Dpofirs AC Voltage Regulator, consider the following maintenance points:
- Cleaning: Keep the unit clean and free from dust and debris, especially around the ventilation openings and fan. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure the fan and ventilation holes are not obstructed to allow for proper airflow and heat dissipation.
- Connection Checks: Periodically inspect all electrical connections for tightness and signs of wear or corrosion. Tighten any loose connections.
- Environmental Conditions: Operate the device within its specified environmental conditions (temperature, humidity) to prevent premature failure.
There are no user-serviceable parts inside the unit. Do not attempt to open or repair the regulator yourself.
