?
The ? 5V/2A ? AC ‐ to ‐ DC ? power ? supply ? that ? comes ? with ? the ? Quick ? Start ? board ? is ? plugged ? into ? the ? Power ? Jack ?
(J1) ? on ? the ? board ? as ? show ? in ? Figure ? 1 . ? If ? the ? original ? power ? supply ? is ? lost, ? it ? is ? possible ? to ? use ? a ? substitute ?
power ? supply ? for ? the ? Quick ? Start ? board. ? Voltage ? above ? 5.5V, ? and ? below ? 12V, ? will ? trigger ? the ? Over ‐
Voltage ? protection ? circuitry ? on ? the ? board. ? It ? is ? not ? recommended ? to ? use ? a ? higher ? voltage ? since, ? in ? the ?
event ? of ? a ? failure ? to ? the ? protection ? circuitry, ? damage ? to ? the ? board ? will ? result. ? A ? voltage ? supply ? above ? 12V ?
will ? damage ? the ? PMIC ? part. ?
