16:23:27

Transformer is 500:57 instead of 10:1 to account for the filter stage later. Diode bridge rectifies the full wave. 4-stage π filter with frequency cutoff of 12 Hz and 4.8 kOhm characteristic load impedance (2 Watts @ 12 Volts). Voltage regulating reverse biased zener diode set to 12 Volts.

How to set voltage of AC source, there is only option to change frequency.

@ankityadav Tap on the box which says "Frequency 60 Hz" and it will show additional parameters. Just keep in mind that this is Peak Voltage, not RMS Voltage. You can get the Peak Voltage by multiplying the RMS Voltage by the square root of 2.
