## 一般說明

The Automotive Fundamental Electrical Circuits Unit, "AV-ELC", provides a practical solution to the introduction of electricity in the automotive field with a group of common circuits used by the automobiles today.

The circuits included in the "AV-ELC" are focused on different functions, so there are power supply circuits, rectifier circuits, lamp circuits and resistor circuits, capacitor circuits and logic gates circuits. All of these circuits are designed to provide a good introduction to automotive electric systems.

The "AV-ELC" unit is mounted on a metallic plate that can be used alone or assembled on the EDIBON workbenches.

All circuits included in the unit are isolated to understand the function of the circuits separately. Each circuit has different test points accessible through 2 mm standard lab sockets.

The "AV-ELC" circuits include a series of faults that can be inserted to different components of each circuit to allow the students to detect and understand common failures of the electrical components.

The "AV-ELC" unit is provided with a set of practical exercises, through which the student will understand how the fundamental electric circuits used in the automotive field works.
