1 f Cyclo Converter Trainer

SKU: 8518 Category:

ADTRON?s Model 8518 Single phase Cycloconverter trainer kit is versatile and standalone trainer kit. It is useful for demonstration of working of a cycloconverter and control the speed of motor. The circuit consists of mains synchronization, ramp based firing circuit, Divide by 2, 3, 4, and 5 circuit and power circuit using SCR?s. A pot to observe the phase control can be demonstrated on a resistive load. Speed control of a small AC motor can also be demonstrated. The circuits are all enclosed in an elegant metal cabinet with a well spread intelligently designed circuit layout on the front panel. Multicoloured test points are provided at various stages in the circuit to observe the voltages and waveforms. A comprehensive Instruction Manual complete with Theory, operating details and Observation table is also provided along with the unit.
