Experimental training board has been designed specifically to study the silicon controlled rectifier phase firing and D.C.control characteristics. It is atraining aid for advance studies in control circuits. Practical experience on this board carries great educative value for science and engineering students. Object: 01. To study the D.C. gate control characteristics (firing characteristics) of aSCR. 02. To study and plot the anode current characteristics of aSCR. 03. To measure the holding current of aSCR. 04. To study the plot the phase firing characteristics of aSCR. Features: The Board consists of the following built-in parts: 01. 0to 50V D.C. at 50mA, continuously variable Power Supply for Anode. 02. 0to 3V D.C. at 50mA, continuously variable Power Supply for Gate. 03. 0-10V A.C. at 50Hz, variable Power Supply for Anode. 04. D.C. Voltmeter, 65mm rectangular dial with switch selectable ranges of 1V and 50V. 05. D.C.
