Triac based Indecent lamp dimmer is a simple circuit and it does not requires additional power supply, works directly with 110V AC or 230V AC.
It is a low cost dimmer circuit for adjusting the light brightness of incandescent, Halogen Lamp, Light Bulb load up to 250 W.
Features:
- Input supply: 230 VAC or 110 VAC
- Output: 250 W
- Triac controlled
- On board Potentiometer for adjusting level
- Power Battery Terminal (PBT) for easy input / output connection
- Four mounting holes of 3.2 mm each
- PCB dimensions 40 mm x 34 mm
Circuit description
This kit consists of BT 136 Triac, resistors and capacitor. CN1 connector is for Load connections and CN2 connector for power supply connections.
BT136: It is a sensitive gate Triac, used in general purpose bidirectional switching and phase control applications where high sensitivity is required.
DB3: It is a DIAC that functions as a trigger diode with a fixed voltage reference. It can be used in conjunction with Triac for simplified gate control circuits or as a starting element in fluorescent lamp ballasts
Working principle
This kit is used as a Light dimmer kit. It is used to adjust the brightness of the Halogen Lamp, Light Bulb up to 250 W. A power supply of 230 or 110 VAC is supplied to the kit at CN 2 connector and a light bulb is connected at the CN 1 connector. Using the POT we can adjust the brightness of the bulb.
Applications
It is used to adjust the brightness of incandescent, halogen lamp, light bulb up to 250 W.
