About this item

  • Wide Application: Router speed controller can regulate speed, temperature, voltage and light, which is suitable for US standard A and B plugs, widely used in exhaust fans, electric furnaces, angle grinders, marble machines, blowers, Note: It can't be used in electrical appliances with circuit boards and capacitance electronic components, such as microwave ovens, induction cookers, rice cookers, water pump, washing machines, LED energy-saving lights etc
  • High Quality Material: Fan speed controller uses high-quality ABS plastic insulated flame-retardant shell, which is not discolored, deformed, cracked, high temperature resistant, The internal fittings are made of thickened phosphor bronze, which is safe and reliable in quality and has a longer service life, Note: Your device's startup current should be less than 15A. If it exceeds 15A, this product cannot be used
  • High Precision Display: Rheostat variable speed control 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
  • Overload and Overvoltage Protection: Voltage controller is equipped with an independent switch to control voltage, with overload and short circuit protection function, When the instantaneous current exceeds 15 amperes, the switch will automatically power off, thus protecting the controller, You can also judge the working status of the switch through the indicator light
  • Back Hook Design: In order to facilitate the operation of the angle grinder, we specially designed a hook on the back of the governor, through which you can hang the governor on the tool bag of the tool kit, which is convenient to carry and more convenient to use, plug and play, simple and practical



Product Description

AC Motor Speed Controller

Note: To achieve normal speed regulation, the following conditions need to be met:

1. Carefully calculate the starting current of your motor: The starting current of the motor is generally 4-7 times the rated current

2. Your device's startup current should be less than 15A. If startup current exceeds 15A, this product cannot be used, please confirm the starting current of your device to ensure its suitability

3. This product is only suitable for adjustable speed motors. Some motors do not support step-down speed regulation. Please confirm if your motor can be used (the speed regulation performance supported by the product varies for different motors)

I’ve purchased three of these. One was DOA - Amazon replaced it promptly. The other two function and are nice at the surface level, both after extened multi hour continuous use end up overheating. They trip an internal circuit and turn off. They function again once cooled. Met: if you are using intermittently or for short periods they work just fine. But for extended use under load they have hearing problems.

Pros: This is a very nice addition to the home workshop, enabling variable speed control to most power tools. I use this device to slow down my bench grinder and my wire wheel, when their native speed is too high for some applications. The controller is able to support up to 15 amps, which is adequate for most home use. To allow a motor to overcome starting inertia, it is best to set the dial on the controller to full voltage, then switch on, and gradually reduce power as needed.The included power protection circuit is also a nice way to avoid burning the device out if accidentally used for a 20 amp motor.Cons: The device is a little lightweight. I owned a similar device which only would operate motors up to 8 amps, so it was limited, but the heft of the device was more substantial.
