To Trigger a SCR by using a LDR Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12891
Indian Lab Suppliers supplies the To Trigger a SCR by using a LDR (Product ID: 12891) as part of its electronics engineering lab equipment range. It shows an SCR being fired by light falling on a light-dependent resistor (LDR).
Quick Answer
The LDR is mounted on the panel in the SCR gate circuit, so a change in light level changes its resistance and the gate current. Two potentiometers set the light intensity and the trigger sensitivity, and the circuit is powered by an internal 6 V AC, 2 A supply. The board runs from 230 V ±10%, 50 Hz mains, weighs about 3 kg and measures W 340 × H 110 × D 210 mm.

Frequently Asked Questions
How does light fire the SCR?
Light lowers the LDR resistance, changing the gate current until the SCR triggers.
Can the trigger point be adjusted?
Yes, with the sensitivity potentiometer.
What supply does the circuit use?
An internal 6 V AC, 2 A supply.
