This trainer is intended to study the characteristics of SCR, TRIAC, DIAC and MOSFET devices. In order to facilitate the experimental procedure, necessary support peripheral components like lamp load is provided on the system for interconnections. In order the observe various waveforms of the devices on oscilloscope, an external 12 AC reference is available on board. This trainer has all the necessary components like potentiometers, switches, Transformer, lamp load etc is provided. These are required to conduct all the experiment of the devices.

Note: (a) An external current meter in the range of 25mA AC to 2A is required to measure respective currents, (b) a dual beam oscilloscope, and (c) a high impedance volt meter are essential requirements.
