AC/DC Electrical Circuit Trainer

Components

The following components are fixed to the front panel of the AC/DC Training System:

– DC power source (protected)

– AC power source (protected)

– A selection of resistors

– An inductor, parallel-connected to a fluorescent light

– Two capacitors

– Transformer

– A selection of switches: SPST, SPDT, DPDT, NO push button, NC push button, selector switch, knife switch

– DC relay

– AC relay

– A selection of indicator lights: green, yellow, red

– Potentiometer

– DC motor

– Solenoid

– Buzzer

– Circuit Breaker with test components

– Fuse The AC/DC Training System also includes the following individual components that can be fixed to or stored in the case lid.

– Two multimeters

– Connection leads set

– Compass

– Iron rod (for electromagnetism experiments) The AC/DC Training System also includes six built-in faults that each can be individually inserted in the system using a toggle switch. These faults are designed to test and improve the troubleshooting skills of students.

Courseware

Through theory and hands-on exercises, the AC/DC Training System fully covers the following topics: nature of electricity, Ohm’s law, Kirchhoff’s voltage and current laws, using measuring instruments, solving series and parallel circuits, electromagnetism, electrical distribution, and troubleshooting electrical circuits.

The courseware included in the AC/DC Training System consists of two student manuals providing comprehensive theory presentations, guided, easy-to-understand lab procedures, and review questions. Two instructor guides that include both the content of the student manuals as well as the results and answers to questions is also included with the system.

The AC/DC Training System comprises the most common electrical components in modern electrical circuits, easy to access and safe for student experimentation. Two 24 V power supplies provide dc power and ac power. The training system itself can be powered from a standard ac wall outlet.

Carrying Case

The carrying case containing the AC/DC Training System is designed for maximal protection of the system components while still allowing easy transportation. Transport is facilitated by the sturdy wheels and telescopic handle. The lid of the carrying case is fixed into place with durable plastic locks, but can be removed easily when performing experiments, allowing access to the components. The lid also includes a storage compartment for the leads in the system, as well as for other individual components. The two multimeters included in the training system can also be conveniently fixed on the interior of the lid to protect them from damage. The external form of the case enables multiple units of the training system to be conveniently and securely stacked one atop the other when the training system is not being used. The tight, waterproof, and sturdy case prevents damage to the equipment during prolonged storage periods.

The curriculum included in this training system is divided into two courses designed so that students learn progressively the different concepts important to the study of dc and ac circuits. The two courses are divided into exercises that each include all the theory required to the study of a particular topic, as well as hands-on experimentations. These experimentations reinforce the theoretical concepts and help students develop the skills necessary to work in the field of electricity. Whenever possible, the curriculum also introduces students to troubleshooting electrical circuits.
