Diymore AC 220V 4000W High-Power Motor Speed Regulator 10A Fan Speed Controller Angle Grinder Speed Control with Overload Protection

Features1. Utilizes a high-power SCR voltage regulator to achieve smooth, stepless speed control. Allows flexible adjustment of speed, temperature, voltage, and light intensity with a sensitive response2. Built-in surge protection, spike suppression, and RC absorption circuits effectively protect the high-voltage SCR; paired with a flame-retardant insulated housing that withstands high temperatures, multiple layers of protection ensure long-term stable operation3. Features genuine SCR chips, precision resistors, and high-voltage capacitors, combined with an all-aluminum heat sink and high-temperature-resistant FR-4 circuit board for efficient heat dissipation and long-lasting durability4. Equipped with a multifunctional industrial socket featuring thickened copper contacts for reliable connection; includes mounting holes for either horizontal placement or suspended installation, adapting to a variety of usage scenarios5. Suitable for a wide range of resistive and inductive load devices, including heating elements, electric furnaces, tungsten lamps, small motors, electric irons, and electric drills; quiet, energy-efficient, and highly practicalParameterProduct Name: Electronic Voltage and Speed RegulatorInput Voltage: European Standard AC 220V / U.S. Standard AC 110VPower Frequency: 50/60 HzOutput Voltage: European Standard AC 0–220V adjustable – U.S. Standard AC 0–110V adjustable (output voltage display)Maximum Power: 4000W (suitable for 2000W resistive loads)Adjustable Voltage Range: 0–220V; guaranteed to be adjustable under load conditions—voltage can be reduced to 0V, and increased in 10V increments starting from 9ARated Current: 10A (AC 220V) / 15A (AC 110V)Main FunctionsThis unit features temperature control, lighting control, speed control, and voltage control.Temperature Control: Resistors, heating wires, heating tubes, electric furnaces, etc.Lighting Control: Dimmable incandescent bulbs, dimmable LED lights, high-voltage halogen lamps, and tungsten filament bulbs, etc.Speed Control: Fans, exhaust fans, electric drills, angle grinders, etc.Voltage Regulation: Reduces mains voltage and adjusts load power.Not suitable for soft-start/slow-start voltage regulators or inductive transformers. Do not use with standard LED lights or household appliances!!!Precautions1. When the unit is in a no-load state, the measured output voltage is a virtual value. A load with a power rating greater than 20W must be connected to measure the correct output voltage (note: apply the load first, then adjust the voltage).2. Please use within the rated power and voltage ranges; this device is for AC use only.3. The 4000W mentioned above refers to the maximum power under resistive load conditions. Inductive loads are one-third of resistive loads. Resistive loads include tungsten filament lamps and heating wires, while inductive loads include series-connected motors. Additionally, exercise caution when using this device with electronic products such as circuit boards.4. Slight heating during operation is normal; please use in a dry, well-ventilated area.5. This product has a flame-retardant plastic housing and must be safely grounded. The power outlet must also be grounded.6. This unit is not suitable for use with voltage regulators that control operating voltage, soft-start, or slow-start functions.Package includeMotor speed controller *1Hook *1
