We have gained immense expertise in offering UJT Relaxation Oscillator to respectable clients. The offered range aids in studying the electrical characteristics of uni- junction transistor. Ideally utilized for relaxation oscillator, waveform & pulse generators and firing circuits of SCR’s and TRIAC’s, the offered products are also applicable for making designing firing circuits and control circuits for thyristors.
Objects:
- Study of zener diode as voltage regulator
- Study of static emitter characteristics of UJT- uni-junction transistor on oscilloscope
- Study of effect of V on peak point and valley point voltage and valley point current
- Operation of UJT relaxation oscillator and its use as SCR trigger circuit
- Control of UJT trigger pulses with shunt transistor
- Study of variations in gate resistance & capacitance, resistance of source & drain and their effect on trigger pulse characteristics of UJT relaxation oscillator
- Various configurations of UJT relaxation oscillator type 1(low output impedance), type 2 (moderate output impedance) and type 3 (high output impedance)
