Experimental Training Board has been designed specifically to study the characteristics and applications of a DIAC. DIAC is extensively used now a days in power control circuits.

Practical experience on this board carries great educative value for Science and Engineering Students.

Object:

01. To plot V-I Characteristics of a DIAC and study the following :
1.1 Breakover voltage, VBO.
1.2 Negative resistance region.
1.3 VBO symmetry and delta V
02. To study the applications of a DIAC as :
2.1 Saw tooth waveform generator.
2.2 Pulse train generator.

Features:

The board consists of following built-in parts:
01. 0-50V D.C. at 50mA, regulated Power Supply.
02. 45V A.C. at 50mA, unregulated Power Supply.
03. D.C. Voltmeter, 65mm rectangular dial to read 0-50V D.C.
