DC Position Servo System Demonstrator Model PCT 014
Sci-tech DC position Servo System Demonstrator Model PCT 014 is a versatile self – contained stand – alone demonstrator, useful in the study and demonstration of the principle and working of a DC position Servo System. It consists of a common potentiometer with calibrated dial as master or input transducer and a rebalance potentiometer to convert output position into a voltage signal along with specially designed DC motor with suitable coupling, Amplifiers Pre – amplifier (Differential Amplifier), Summing amplifier of adjustable Gain & Span (Error Amplifier) and Power amplifier for driving DC motor on basis of error signal.
Various controls for different parameters are provided. It is a highly accurate, highly sensitive demonstrator with good repeatability, linearity and 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 and voltages. It is strongly supported by a comprehensive instruction manual complete with theory & operating details.
