The circuit has been constructed to provide an in-circuit system that will test the integrity of electronic components such as Silicon Controlled Rectifiers, diodes, and PNP or NPN transistors. 4093 – ...
The circuit in the diagram is a very handy tool for rapidly checking all kinds of thyristor (SCR, triac, …). In case of a triac, all four quadrants are tested, which is done with S3, while in case of ...
Designers often test prototypes with a variable-voltage bench power supply. If they leave the bench for any length of time, someone may borrow the supply or otherwise change the voltage to a level ...
