Product Code : SCL-EELE-12896
Indian Lab Suppliers supplies the Single phase Half Wave Controlled Converter (Product ID: 12896) as part of its electronics engineering lab equipment range. It is a single-SCR half-wave controlled converter with UJT firing, used to obtain and study its output waveforms.
Quick Answer
A UJT oscillator, powered by a 9 V DC, 100 mA zener-regulated supply, fires the SCR through a 1:1 pulse transformer, and a potentiometer moves the firing angle. The SCR feeds a 40 W, 230 V lamp from a 50 W, 230 V AC isolation transformer, so students can see the lamp dim as the conduction angle shrinks and record the load-voltage waveform. The board runs from 230 V ±10%, 50 Hz mains; the lamp circuit is at mains voltage.

Frequently Asked Questions
When does the SCR conduct?
Only in the positive half cycle, from the firing angle until the current falls to zero.
What is the load?
A 40 W, 230 V lamp.
Why is an isolation transformer used?
It isolates the circuit and connected instruments from the mains.
