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:

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.
