A.C. Position Servo System Trainer Unit

SKU: 2003 Category:

SALIENT FEATURES :

AC Positions Servo System Demonstration Unit 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 Servo meter 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 circuit layout on the front panel. Multi – coloured test points are provided at various stages in the circuit to observe waveforms & voltages. It is strongly supported by a comprehensive instruction manual complete with theory & operating details.
