Sci-tech AC position Servo System Demonstrator Model PCT 001 is a self-contained stand – alone demonstrator, useful in the study & demonstration of the principle & working of a AC Position Servo System. It consists of a potentiometer with calibrated dial as master or input transducer & a rebalance potentiometer to converts output position into a voltage signal along with specially designed two phase AC Servomotor with suitable coupling, feedback path, summing amplifier, power amplifier.
Various controls for different parameters are provided. It is a highly accurate, highly sensitive demonstrator with good repeatability, Linearity & fast response. The unit is housed in an elegant cabinet with a well spread intelligently designed multicoloured layout on the front panel. Multi – coloured test points are provided at various stages to observe waveforms & voltages. It is strongly supported by a comprehensive instruction manual complete with theory & operating details.
