Feature:1. Input and Output Voltage: Compatible with 120V or 220V power input, with a maximum current of 18A, the output voltage is 0 to 120V when 120V is input, and 0 to 220V when 220V is input, the output voltage is continuously adjustable.2. Wide Application: Applicable to excitation motors, electric tools and resistive loads, such as fans, handheld routers, electric kettles, electric stoves, electric soldering irons, etc.3. High Power: The maximum power for connecting inductive loads (such as fans and routers) is about 1500W, and the limit power for connecting resistive loads (such as electric furnaces and heating wires) is 1500W.4. Sturdy Shell: The controller adopts a sturdy galvanized iron shell, which is not easy to be deformed or damaged, protects the internal parts from being damaged.5. Easy to Install: The variable speed controller has holes on the back, which is convenient for easy installation and fixation.Specification:Item Type: Variable Speed ControllerShell Material: Galvanized Iron ShellModel: CCMTKAC 4000Input Voltage: 110-240VPlug: US plugSize: Approx. 130x85x53mm/5.1x3.3x2.1inRated Current: 9A (limit current 18A)Output Voltage: AC10-120V (the lowest adjustable voltage is related to the load). Only when the load is connected can the output voltage change be detectedVoltage Regulation Range: AC0-120V stepless voltage regulation (with load), with about 10V voltage riseRated Power: It is recommended to use within 1500W..Package List:1 x Variable Speed ControllerNote:1. Warning, not suitable for intelligent appliances with complex circuit boards.2. Note that 1500W is the maximum power when working under ohmic load.
