Circuit Documentation

Summary

The circuit in question appears to be a power supply unit that takes an AC input and converts it to a regulated DC output. The AC supply is stepped down using a power transformer from 220V to 24V. The reduced AC voltage is then rectified using a bridge rectifier to convert it to DC. This DC is then smoothed using electrolytic capacitors to reduce voltage ripple. A voltage regulator is used to provide a stable DC output, and a potentiometer is included for adjustable voltage output. The circuit also includes a resistor for current limiting and a 7-segment panel voltmeter for voltage display.
