About this product

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)
  In built parts:  
  • An isolation transformer 230 V A.C. At 100 mA. This protects external instruments from damage if they are not isolated
  • 20V D.C. at 100mA, IC regulated power supply internally connected
  • Bridge rectifier and zener regulator
  • Potentiometer for frequency control
  • Two band switches for selecting different value of resistance and capacitance
  • Pulse transformer 1:1:1
  • Adequate no. of other electronic components
  • Mains ON/OFF switch, fuse and jewel light
  Specifications:  
  • The unit is operative on 230 V ±10% at 50 Hz A.C. mains
  • Adequate no. of patch cords stackable 4 mm spring loaded plug length ½ meter
  • Good quality, reliable terminal/sockets are provided at appropriate places on panel for connections/observation of waveforms
  • Strongly supported by detailed operating instructions, giving details of object theory, design procedures, report suggestions and book references
  • Weight: 3 kg. (approx.)
  • Dimension: W 340 x H 110 x D 210
