Use Cases

Arduino & Microcontrollers – Step-down transformers (6–12V) for regulated 5V power supplies.

DIY Power Supply Projects – Center-tap transformers for rectifier + filter + regulator circuits.

Audio Amplifiers – 12-0-12V or 18-0-18V transformers used in TDA2030, TDA7294, LM3886 amps.

LED Drivers – Isolated AC to low-voltage DC conversion.

Robotics – Transformers feeding high-current motor drivers (with proper rectification).

Basic Wiring Diagram

AC Mains (230V) | | [Primary Coil] | | ---------------- || <- Magnetic Coupling ---------------- | | [Secondary Coil] → AC Output (6V / 9V / 12V / CT) | | After the transformer: Secondary AC → Bridge Rectifier → Smoothing Capacitor → Voltage Regulator → DC Output

Safety Note

Never touch the primary (230V AC) terminals while powered.

Use proper insulation, heatshrink, and fuse protection.

Mount the transformer securely to avoid vibration damage.

Use a multimeter to verify output before connecting to circuits.

Ensure adequate ventilation for high-wattage transformers.

Video Tutorial: How to Test a Transformer

Here’s a simple step-by-step video guide outline you can use to create or upload as a tutorial:

Introduction – Types of transformers (step-down, CT, audio).

Tools required – Multimeter, insulated wires, lamp tester (optional).

Testing the primary coil – Check continuity using a multimeter.

Testing the secondary coil – Measure resistance of each output winding.

Live testing – Carefully measure AC output voltage on secondary (with isolation & safety).

Testing center-tap outputs – Measure between CT and each terminal.

Common faults – Overheating, burnt windings, open coils.
