Variable Speed Controller AC Motor Speed Control for Exhaust Fan Router Rheostat Drill Electric Motor, with 15A Overload Protection Switch and LED Display Screen, AC 110V 120V or 220V 240V - GMURA, SDKZQQ03-D

• Wide Application: Router speed controller can regulate speed, temperature, voltage and light. Applicable to resistive loads, electric tools and excitation motors, such as router rheostat exhaust fan, electric motor. Note: Can't be used for electrical appliances with circuit boards and capacitive electronic components, such as microwave ovens, induction cookers, rice cookers, water pumps, washing machines, LED energy-saving lamps, etc High Precision Display: Fan speed controller adopts precision pressure regulating knob for voltage regulation, with high accuracy and good stability, Control accuracy can reach 1 volt, Through the digital display screen, you can accurately understand the working voltage of the machine, LED light makes the real-time voltage number clearer High Quality Material: Rheostat speed control is made of high-quality PC/PP insulated flame-retardant shell, which is not discolored, deformed, cracked, high-temperature resistant, and has a longer service life. The internal parts are made of thickened phosphor bronze, with stable performance, high accuracy, and more safe to use, multiple cooling holes around, faster heat dissipation, universal socket on the side, applicable to plugs of various specifications Automatical Protection: Normal Current 9A, Maximum Current 15A, Input Voltage AC 110~120V or 220~240V, Output Voltage AC 0-120V or 0-220V, electronic voltage regulator has overload and short circuit protection functions, When the instantaneous current exceeds 15 amperes, voltage controller will automatically power off to protect the controller, You can also judge the working status of the switch through the indicator light Maximum Power: The maximum power of connected resistive load is 2000W, such as electric furnace. The maximum power of connected inductive load is about 1200W, such as exhaust fan. The maximum power under ohmic load is 4000W, and the inductive load is about 1/3 of the ohmic load, so only devices within the range of 40-2000W can be connected
