Electrical Characteristics
The LSIU80ALVD maximum power requirement, including SCSI
TERMPWR, under normal operation is as follows:
Under abnormal conditions such as a short on SCSI TERMPWR, + 5 V
current may be higher. At temperatures of at least 25
°
C a current of 4 A
is sustained no longer than 30 seconds before the self-resetting
TERMPWR short circuit protection device (F1) opens.
