Product Code : SCL-EELE-12820
Indian Lab Suppliers supplies the Lamp Dimmer (Product ID: 12820) as part of its electronics engineering lab equipment range. It is a trainer that shows how thyristor phase control dims a mains lamp.
Quick Answer
Two firing methods are built in and chosen with a switch: a DIAC-TRIAC circuit and a UJT circuit, with gradual firing-angle control up to 180°. The load is a 100 W milky-white lamp, supplied, switched by a BT136 TRIAC or a 600 V / 16 A SCR. An internal isolation and attenuator circuit lets students view the high-voltage waveforms safely on an oscilloscope. The lamp circuit runs at mains voltage and the bulb gets hot, so make changes only with the supply off.
