Characteristics of Bidirectional Diode Thyristor (DIAC) and measurement of its parameters, Model: D – 10


  • Builtin   regulated,   short  circuit  proof  power  supply  suitable  to  the  experimental  set – up.
  • Circuit  is  drawn  on  a decorated  bakelite  sheet to  facilitate  better  and  clear  understanding.
  • A  complete  working  manual  containing  operating  instruction,  theory  and  circuit  details  will  be  supplied  alongwith  experimental  set - up.
  • Stackable  type  patch  cords  suitable  to  the  terminals  are  provided  with  the  board  for  easy  interconnections  and  longer  working  life  of  the  terminals.
  • 50,  Hz  step  down  A.C.  Signal  for  both  anode  and  gate  are  builtin.
  • Both  AC  and  DC  control  of   TRIAC  firing  can  be  studied. 
  • Weight : 1.5Kg Approximately
  • Dimension : 210mm × 280mm × 82mm
