Study of UJT and UJT Relaxation Oscillator with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12879
Power Electronic Training Board has been designed specifically for the study of Electrical Characteristics of Uni- Junction Transistor. The UJTs are widely used for Relaxation Oscillator, waveform & pulse generators and firing circuits of SCR's and TRIAC’s. This Training Board can also make use for designing firing circuits and control circuits for thyristors.
Practical experience on this board carries great educative value for Science and Engineering Students.
