Objective of this experiment: To construct Lamp dimmer using Diac & Triac. To build Lamp control circuit using Triac. The gate of the triac is triggered by diac (bi-directional device). The firing angle can be varied by the gate control simultaneously the brightness of the lamp can be varied. Built in power supply: 130 VAC/50Hz Input Supply: 230 VAC/50Hz mains operated.
