In this article, we are going to explain the 1000W BT139 TRIAC light dimmer circuit by connecting the power line where a raised cardiac dimmer circuit triggered 500k can be adjusted by a potentiometer. It is a commonly used circuit that is used in fan dimmers also. Fan dimmers that are available in the market are very low power, but this circuit can control easily 1000W.

Light Dimmer Circuit 1000 Watts Using BT139

Sometimes we are required to control the power of incandescent lamps. This simple Light Dimmer can control power up to 1000W. This circuit operates on the phase-control principle. The power-operated components DIAC and TRIAC are used for controlling the output power with some other electronic parts like resistors, capacitors, and potentiometers.

Components Required For Light Dimmer

  • BT136 TRIAC
  • Pot 500k
  • Resistor 3.9k
  • Capacitor 100nF
  • Capacitor 10nF
  • DB3
