Learn how to build a voltage regulator dimmer! In this video, I show a detailed step-by-step guide on how to build a variable voltage regulator of 5,080W at 127V and 8,800W at 220V.
It is ideal for controlling the rotation of rotary motors such as fans, drills, Makita tools, sanders, grinders, among others. It can also be used to regulate the temperature of resistors such as electric showers, sealers, electric ovens, soldering irons, incandescent lamps, etc.
Materials and components for building this dimmer:
1 B200K potentiometer
1 10K 1/4W resistor
1 DB 3 diac
2 100 NF, 400V polyester capacitors
1 BTA 41 600b or BTA 16 600b
1 Heat sink.

A dimmer is a widely used device for controlling electrical voltage, allowing for variation in the power delivered to different equipment. Its main function is to control the light intensity of lamps, making it possible to adjust the brightness according to the needs of the environment, providing energy savings and increasing the lifespan of the lamps.
In addition, the dimmer can also be used in other applications, such as controlling the input voltage of transformers. By regulating the input voltage, it is possible to control the output voltage, which is quite useful in devices such as pyrographs, which require precise control for burning wood and other materials.
Other common applications for dimmers include:
Electric showers: where the dimmer can regulate the water temperature by adjusting the power used by the heater.
Packaging sealers: by adjusting the heating level, the efficiency of package sealing can be improved.
Fans: allow control of the blade speed, offering a personalized adjustment for comfort.
Therefore, the dimmer is a versatile device that is not limited to lighting control, and can be applied to various types of equipment that require power or voltage adjustment.
