  • Does what is says on the tin.

    Working OK so far. I am using it to control the speed of a brush motor (1500w table saw). Not sure it would work well on induction motors, might cause overheating of motor or controller so haven't risked it. The one design flaw with it is the flap over the terminals. This wont open without bending or removing the cover. I removed mine temporarily - no big deal. As it is all metal, make sure the case is properly earthed, and ideally fitted inside or under some other protection.

  • A good speed controller.

    It is being used to control a large frame size 200watt 230volt 4000 rpm AC motor on an engraving machine. It works exactly as it should. This is a good speed controller.

  • Very useful ac motor controller.

    Used to control the speed of my grinder to remove stubborn ivy remnants, because normal revs were eating plaster also. Did the job well and has many other uses. I built one myself many years ago and missed it after asking overloading it. Now we have protection for prevention. Great value.

  • Come upo to exppectations

    I use it to control a led lamp. Far better than cheaper controller (50-220V), becouse really can control to 0 V and noise is very low when it work (I can hear only if I take my ear very close to the controller (the controller not in box).

  • Not recommend!

    Unstable voltage regulation. The control knob has more than half the idle rotation. There is a risk of damage to the electromotor which regulates voltage and rotation. For example, an angle grinder can not be properly regulated. Nor any other similar electric tools.

  • Zero voltage

    One of the things the product does not do is to reduce the voltage to 0, I had expected that when reducing to its lowest setting the Motor would stop, this was not the case, would have been helpful if this was explained

  • First class unit at a great price

    This unit allows you to turn regulate the speed of a bench grinder which allows you to sharpen lathe turning tools without overheating the steel. It costs a fraction of the price of a speed controlled machine . And if you connect a 13a socket to this unit it allows you to plug in various machines.

  • Does the job

    I was very pleasantly surprised that this device works precisely as I had hoped despite its rather cheap appearance. It allowed me to control the speed of a bouncy castle blower electric motor in order to modulate airflow for other applications.
