Triggering Circuits for SCR

Product Code : JL-PET-1430

Triggering Circuits for SCR

  • Power Electronic Training Board has been designed specifically for the study of SCR Triggering circuits.
  • Practical experience on this board carries great educative value for Science and Engineering Students.


To study the SCR Triggering circuits using:

  • Resistor (R) Triggering circuit
  • Resistor - capacitor (R-C) Triggering circuit
  • Uni-junction Transistor (UJT) Triggering circuit (UJT relaxation Oscillator)
  • Half-wave controlled rectifier
  • Full-wave controlled rectifier


The board consists of the following built-in parts:

  • 35VA.C. at 100mAA.C. Power Supply
  • Bridge rectifier for making D.C. voltage
  • Two Silicon controlled rectifier (SCR)
  • Uni junction Transistor
  • Pulse transformer 1:1
  • Two potentiometer for varying load
  • Two potentiometer one for controlling SCR firing angle and other for controlling UJT firing angle
  • Adequate no. of other Electronic Components
  • Mains ON/OFF switch, Fuse and Jewel light
  • The unit is operative on 230V ±10% at 50Hz A.C. Mains
  • Adequate no. of patch cords stackable 4 mm spring loaded plug length ½ metre
  • Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections/ observation of waveforms
