Module TPS - 3321

Electricity and Semiconductors Training System




Technical Characteristics

The trainer is enclosed in a metal case, which has a wide experiment platform printed circuit board (22cm x 35 cm). This ensures easy handling and good visibility of the components.

The components are located on the board which has a silkscreen print of the analytical circuit and component symbols. The central part of the experiment board includes all the circuit block drawings and all the hands on components and test points.

The protected components are located on the circuit board, clearly visible to the student and protected by a sturdy transparent cover.

The system includes a built in power supply with +12V, +5V, variable DC voltage, and AC voltage outlets. An included low voltage external AC power adapter feeds the system.

The system includes:
• Diodes (Silicon, Germanium and Zener(
• Resistors, Potentiometer, Rheostat
• Thermistors (NTC & PTC), LDR, phototransistor
• Inductors, capacitors and variable capacitors
• Transistors (NPN, PNP, JFET, MOSFET)
• SCR, TRIAC, DIAC, UJT
• Transformer, Regulator
• AC Motor and DC Motor
• SES Lab unit with two-channel scope and function generator, which communicates with a PC to control the function generator and oscilloscope display, including spectrum analysis
• PC software (OPTIONAL (

The system has an optional add-on troubleshooting card that communicates with the instructor’s PC via the SESML network.

Using multiple choice student exams, the student answers the exam questions with the trainer’s keyboard and display. The instructor can build a database of students, classes, and exam answers and can monitor the students’ exams.

Objectives

This course introduces the student to fundamentals of electricity covering: AC/DC circuits, voltage, current, resistors, capacitors, coils, measurements, electricity laws, electromagnetism, power supplies, semiconductors, motors and generators

The course includes comprehensive hands-on experiments with electronic semiconductors: diodes, transistors (Bipolar and FET), regulators, LEDs, thermistors, LDR, phototransistor, SCR, DIAC, TRIAC, UJT and their applications such as power supplies, amplifiers and power control.



Description
The system is stand-alone containing all the necessary electronic components needed for performing hands-on experiments.

The experiment area is in the central part of the trainer including component drawing, test points, and peripheral outputs and inputs. The circuit board contains visible component circuits protected by a sturdy transparent cover.

The system includes a built in power supply with +12V, +5V, variable DC voltage, and AC voltage outlets.

The system includes the SES Lab unit with a two-channel oscilloscope and a function generator, which communicates with a PC to control the function generator and oscilloscope display, including spectrum analysis.

The built in function generator can also be operated manually, controlled by the embedded micro-controller for sine/triangle, PWM/constant signals.
