AFETY
In the event power is lost to the unit, but a charged capacitor is connected, a
230Ω resistor will automatically be connected to the output terminals, slowly
discharging the capacitor and the "Voltage Present" LED will continue to
function. If the voltage is sufficiently high, the capacitor will also back-feed
the system, allowing it to remain powered in the absence of external power.
