Triac Characteristics

Model HV-EXP2172
Experimental Training Board has been designed specifically to study the characteristics of TRIAC-a Bidirectional Triode Thyristor.Practical experience on this board carries great educative value for Science and Engineering Students. Object: 1.To study the gate characteristics of aTRIAC in the following modes : (a) Mode I+ :i.e. T2 positive with respect to T1 and gate positive with respect to T1 (b) Mode I- :i.e. T2 positive with respect to T1 and gate negative with respect to T1 (c) Mode III+ :i.e.T2 negative with respect to T1 and gate positive with respect to T1 (d) Mode III- :i.e. T2 negative with respect to T1 and gate negative with respect to T1 2.To study the terminal characteristics of aTRIAC in the following modes : (a) Mode I+ :i.e. T2 positive with respect to T1 and gate positive with respect to T1 (b) Mode III+ :i.e. T2 negative with respect to T1 and gate positive with respect to T1 3.To study the following applications of TRIAC: (a) Triac as astatic switch (D.C. control). (b) Control of A.C. with A.C. signal. (c) To measure the holding current of IH. Triac.
