 Region V：Output over current protection (OCP) action. When the output current of the unit is
over limitation, the output voltage steps down. If the failure mode is removed, the output voltage
auto-recovers.
 Region VI：
(1) Input UVLO action. When the input voltage is under 80Vac (Typ) , the PFC_Ctrl signal
changes from high to low, which means that the PFC converter turns off. After ±BC reduces to
300V, the inrush signal changes from high to low at the same time.
(2) When the inrush is low and delays 5mS, the DC/DC_Ctrl changes from high to low, which
means the DC/DC converter turns off.
(3) When the output voltage of DC9010-690G decreases to 13.7V (Typ), the ENA signal changes
from low to high.
The unit turns off through the steps of region VI.
