This is a 2000-watt voltage regulator. 220-volt regulators. Normally, we can not buy these types of voltage regulators. We can find only a fan regulator, but it’s a 2000-watt voltage regulator. We can use this type of regulator for a drill machine, a blender machine, a water heater, Etc.

This is the DIY adjustable voltage regulator for 30 volts and 2 amperes. can control the voltage and amperes. Here, use 2 adjustable volumes to control the voltage and amperes. Here, use a 2N3055 transistor. It’s an NPN transistor. We can also use another transistor.

This circuit can be used only with an AC 220 voltage.

Here, the use of 3 FT1614MJ is an electronic component called a TRIAC (Triode for Alternating Current). It is commonly used to control the AC 220 voltage.
Basic Description
Type: TRIAC (bidirectional thyristor), Manufacturer: Fagor Electronica. Use: Switching and controlling AC loads (like motors, lamps, heaters). A TRIAC can conduct current in both directions, which makes it ideal for AC circuits (220V or 110V).
Key Specifications (FT1614MJ)
The Voltage Rating is 600V
The Current Rating is 16A (RMS)
The Gate Trigger Voltage is ~1.3V
The Gate Trigger Current is ~35mA
The Package is TO-220 (3-pin, through-hole)
The Operating Temperature is -40°C to +125°C
Typical Applications
The Light dimmer circuits, the Fan speed controllers, the Motor control circuits, the Heater control systems, AC switching circuits.
