Transformer an input transformer for the stepping down of the 230v ac power supply.
A typical power supply unit consists of the following.
The most commonly used of type of power supply circuit is the smps switching mode power supply you can easily find this type of circuits in your 12v adapter or mobile laptop charger.
They are just thin plastic rectangular plates or polyester film.
The circuit is design as a mono audio amplifier.
Regardless of the color new boards have one or more layers of conductive copper foil.
Most are blue or tan though you can find a few other colors out there3 as well.
The output from an ordinary power supply is fed to the voltage regulating device that provides the final output.
