This circuit board takes 6 to 30 volts AC or DC as input. If necessary,
it rectifies AC to DC and filters the result, then regulates it's output to a
fixed +5 volts DC. The closely regulated 5 volt output can be used to
power up to ten Signal Controller circuits. Typically, only one Power
Regulator circuit will be needed on a small or medium sized layout.
Additional circuits can be added if many more signals will be lighted.
The power regulator can safely supply up to a half amp of DC. It is equipped with a thermal shutdown that will protect it in case of an accidental short circuit or current draws in excess of an amp.
