SCR Lamp Flacher
SCR Lamp Flasher
- Power Electronic Training Board has been designed specifically to study the use of SCR and TRIAC in D.C. and A.C. lamp flasher respectively.
- The flasher is useful for students of understand the application of SCRs in D.C. flasher, triggered by UJT relaxation oscillator.
- The repetition rate of the flasher can be varied by varying the frequency of the relaxation oscillator.
- This Training Board also makes use of the same SCR D.C. flasher for making the TRIAC ON and OFF in the A.C. power circuit which operates a normal 230V incandescent lamp used as load.
- Practical experience on this board carries great educative value for Science and Engineering Students.
