Product Usage: This electronic voltage regulator has a wide range of applications, mainly including functions such as speed regulation, voltage regulation, temperature regulation, and light regulation. Usage: Adjust the front adjustment knob to the "0" position, connect the product power cord to the AC 220V socket, and the output voltmeter displays the voltage (the voltage displayed at no-load is a virtual voltage, and the correct voltage can be measured only when the load is connected). Connect the electrical equipment to the output socket, slowly adjust the knob, and turn clockwise to boost and counterclockwise to depressurize. Precautions: The peak power of this product module is 4000W, and the maximum power of the resistive load connected to the grounding device should not exceed 2000W. The maximum power of the inductive load should not exceed 500W, and the maximum power of the capacitive load should not exceed 300W. Otherwise, the product may be damaged. Speed regulation of fans with a power of over 550W should have a minimum speed of half. For appliances with a power of over 1000W, when not in use, turn the knob to 0 to avoid excessive current during the next startup and damage to the regulator. Special reminder: 1. The input voltage of this product is AC voltage, and the output is AC voltage. The maximum input value is equal to the maximum output value. It reduces voltage to reduce power, and has no boosting function. This product is not suitable for applications that require precise speed or require very low or very low speeds. 2. Electronic components such as circuit boards in smart appliances cannot be used (such as household water pumps, induction cookers, rice cookers, and ordinary LED energy-saving lights). Only adjust most fans and brush powered tools, and other motors cannot be adjusted separately. If the motor already has gears or has high and low speed lines, connecting the regulator will cause buzzing AC frequency sound or no speed regulation effect. 3. Be careful not to come into contact with children, stay away from ignition sources, and do not insert foreign objects outside the plug into the socket. 4. This product has no waterproof function and is only used indoors in a dry environment. Be careful not to splash water when using in damp places such as bathrooms, kitchens, and fish tanks. Product application scope: * Speed regulation : fan type, brush motor, electric tool type (do not already have gear) * Temperature regulation : electric stove, oven, water heater, heating rod, electric blanket, etc. (with display screen and intelligent type not adjustable) * Dimming : Tungsten filament lamps, incandescent lamps, halogen lamps, insulation lamps, lamp strips, etc. (LED energy-saving lamps with circuit boards are not adjustable)
