Horn Circuit Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-13824
This is a specialized, compact educational trainer
designed to teach the fundamental principles of high-current relay circuits
using the automotive horn system as the primary example. It provides
hands-on practice in assembling, wiring, operating, and diagnosing faults in
common automotive electrical control systems.
Core System Features and Educational Focus
- Relay
Principle Demonstration: The core function is to
demonstrate how a small switch can control a high-current device
using a relay. The system components (coil, iron core, heavy-duty
contacts) are used to illustrate this principle, which applies to horns,
starters, power windows, and cooling fans.
- Safety
and Wiring Practice: Focuses on practical skills:
- Assembling
the circuit on a good quality PCB or common board.
- Emphasizes
the importance of knowing the car's electrical wiring, warning that a wrong
connection may damage your car’s electrical circuitry.
- Component
Flexibility: Notes that the transistor Q1 (used in a
related warning circuit, like the reverse gear switch activation) is not
specific, allowing for the use of any medium power NPN audio transistor,
aiding in troubleshooting and repair practice.
- Operational
Control: The switch S1 is used to simulate a control
input, such as the reverse gear switch of the car.
