The SCR Speed Control Learning System features heavy-duty components like an SCR speed control unit, DC shunt wound motor, and fuse block to give learners real-world practice on SCR speed control skills such as connecting and operating a motor with SCR half-wave speed control, measuring the performance of SCR half-wave speed control, and troubleshooting an SCR speed control circuit. SCR Speed Control Learning System adds to the Electronic Motor Control Learning System to teach variable speed motor control of DC electric motors using Silicon Controlled Rectifier (SCR)-based circuits. These hands-on skills are carefully interwoven with world-class SCR speed control curriculum so that learners understand both the theoretical and practical knowledge that they'll need to be successful. SCRs convert AC voltage into a DC voltage in order to provide efficient variable speed control of DC motors and are widely used within industrial applications such as cranes and machine tool spindles.

The simulator takes into consideration all these components, by analyzing their behaviour and their structure. The extensive use of sensors and actuators comes from the need of the electronic control panels to know in real time the actual values of the physical parameters to be controlled or which influence the behaviour of the car.
In particular, the following components are analyzed:
Position sensors
Oxygen sensors
Temperature sensors
Pressure sensors
Air flow rate sensors
Electro pumps and geared motors
Servomotors
Electro valve
Knock sensors
Electro injectors
Coils
Level Sensors
Inertial sensors.

The Computerized Boiling Point Heat Transfer Unit is designed to display the various types of boiling to change the intensity of the heat flow. The experiment is performed with environmentally-friendly, special low boiling point liquid. A transparent vessel allows to observe the evaporation process at the heated cylinder. More precisely, can be reproduced the nucleate and the film boiling and it can plot the so-called pool boiling which is the basis of the design of the systems with the steam boiler. The cylinder operates as a fire tube heated from the inside. An integrated water-cooled condenser allows for a continuous boiling process. The unit is supplied with manuals that describe each component of the system, installation and utilization procedures and give many exercises. The special liquid used evaporates at low temperatures. An automatic data acquisition and analysis system for Personal Computer allows to take the measurements automatically, to plot the curves on screen or print them out, to store the experimental data on disk or print them.
