OPEN 12V 9V~18V 11V

SHORT 24V 18V~36V 22V
+/- 0.4V
Note:
Usually, the voltage of car battery stays at 13.5V~15V (@ 12V Mode), or at
27V~30V (@ 24V Mode) while the car engine is running. Thus, the
voltage of the car battery can provide enough energy to prevent a cold
crank from starting a car engine when it is higher than 11V (@ 12V Mode) or
22V (@ 24V Mode).
The cold crank will cause the voltage of car battery to drop to 6V (@ 12V
mode) or even lower. It is difficult to maintain a stable +12V power output
to the AEV-6312 and it will cause a cold boot of the AEV-6312.
For the Initial Start Voltage, the input voltage will offer over 11V (@12V
mode) or 22V (@ 24V mode) to the PSU. The PSU will operate at 9V~18V
(@12V mode) or 18V~36V (@24V mode) after the ACC ON.
