    I have used the 4kW SCR voltage regular as a useful means of reducing the speed of my circular saw and angle grinder. Typically, when more control speed is required for special work, this is achieved smoothly and precisely without the loss of too much torque. At the same time, reducing my electricity expense as a bonus. GREAT!

    Speed reducer... I needed it because I had to reduce the revolutions of a tested drill and it works perfectly 👍👍👍 of course it can also be used to reduce the brightness of a lamp for example

    Works very well. Been using it to adjust the power of my electric grill. The rubber of the cord got a bit loose but doesn't affect the performance

    Very good. Exactly what I needed for reducing speeds on a motor that I use for precision drilling. Sturdy and well made. Multiple other uses.
