From inexpensive and affordable materials, you can make your own hands a very simple voltage regulator for 220 V, which is designed to work with electric motors up to 2 kW.
For example, the author of this idea decided to make a simple and compact voltage regulator special for adjusting engine speeds in drills. But also this dimmer is suitable for other electrical appliances: a light bulb, a soldering iron, etc.
In this case, a mainboard with a regulator acts as the main element, which can be ordered on the Aliexpress website. You will also need to buy a suitable-sized case where all components will be placed.
The main stages of work
First, install a board with a regulator inside the box. Then in the case with the help of an electric soldering iron it will be necessary to make a small "window" and install the front panel from the external outlet into it.
At the next stage, it is necessary to install a switch on 220 V. And to install it in the case, you need to drill a hole.
Well, then the wires are connected, which will connect the board with the regulator with a socket and a switch. As you can see, there is nothing complicated here, if you do everything according to the instructions.
