AC Motor Speed Controller 120V 15A 4000W with Overload Protection LED Display Fan Speed Controller Electronic Voltage Regulator

Product Features：
1. Available with various plug standards including European and American standards to adapt to different power systems in various countries and regions.
2. Suitable for high-power tools and equipment such as motors, electric drills, electric furnaces, and angle grinders, ensuring efficient and stable output.
3. Built-in safety protection mechanism automatically cuts off power when the current is overloaded, effectively preventing equipment damage.
4. Widely compatible with industrial and household appliances, such as fan speed control, power tool control, etc.
5. Features a high-strength flame-retardant shell combined with excellent heat dissipation design.

Product Applications:
Speed ​​Control: Fans, brushed motors, power tools (excluding those with built-in speed settings)
Temperature Control: Electric furnaces, ovens, water heaters, heating rods, electric blankets, etc. (non-adjustable for those with displays and smart devices)
Brightness Control: Tungsten filament lamps, incandescent lamps, halogen lamps, heat lamps, light strips, etc. (non-adjustable for LED energy-saving lamps with circuit boards)

Usage Instructions: Before use, turn the adjustment knob to the "0" position. Connect the product power cord to an AC 110V or 220V socket. The output voltmeter will display the voltage (the voltage displayed under no-load conditions is a virtual voltage; a load must be connected to measure the correct voltage). Connect the electrical device to the output socket and slowly adjust the knob; clockwise for increased voltage and counterclockwise for decreased voltage.

Special Reminders：
1. This product uses AC input and output voltage. The maximum input voltage equals the maximum output voltage. Voltage reduction decreases power; there is no voltage boost function. This product is not suitable for applications requiring very precise speed control or very low speeds.
2. This product cannot be used with smart appliances containing circuit boards or other electronic components (e.g., household water pumps, induction cookers, rice cookers, ordinary LED energy-saving lamps). It only adjusts most fans and brushed power tools; it cannot adjust other motors individually. If the motor already has speed settings or high/low speed lines, connecting a regulator will result in a buzzing AC frequency sound or no speed adjustment effect.
3. This product is not waterproof and should only be used in dry indoor environments. Avoid splashing water when using it in damp places such as bathrooms, kitchens, or near fish tanks.

Precautions:
The peak power of this product module is 4000W. The maximum power of the connected electrical appliances should not exceed 2000W for resistive loads, 500W for inductive loads, or 300W for capacitive loads; otherwise, the product may be damaged. For fans with a power rating of 550W or higher, the minimum speed should be half-full. For appliances with a power rating of 1000W or higher, turn the speed control knob to 0 when not in use to avoid excessive starting current upon restarting, which could damage the speed controller.
