The 220V motor speed controller is a versatile device for controlling the speed, voltage, and temperature of various electrical appliances. It is designed for resistive, inductive, and capacitive loads, while providing overload protection. Technical Specifications Material: Flame-retardant plastic Input voltage: 220V AC Output voltage: 0-220V adjustable Frequency: 50/60Hz Rated power: 4000W (maximum resistive load: 2000W) Rated current: 10A Maximum current: 18A (overload protection: 10-15A) Plug type: European plug Dimensions: 12 x 6.6 x 5.6 cm Weight: 480g Compatibility and accessories Compatible with: Fans Inverter motors brushes Gearless power tools Electric ranges Ovens, water heaters, and other heating appliances Incandescent and halogen lamps Installation: Plug the speed controller directly into an electrical outlet for installation. Ensure that the power consumption of the connected appliance does not exceed the specified limits. Instructions To use the variable speed drive: Turn the knob to adjust the speed or temperature as needed. For appliances over 1,000 watts, set the knob to zero when not in use to avoid excessive starting current. Do not use with appliances containing circuit boards or sensitive electronic components. Additional Information Notes: Maximum power should not exceed 4,000 watts. Fans over 550 watts should be set to at least half their maximum speed. Geared appliances may not operate properly with the variable speed drive.
