Overvoltage protection: 20-35% above nominal output
Remote sense:
Compensates for 0.5 V lead drop max. Will operate without
remote sense connected. Reverse connection protected.
Logical Control
Power failure:
TTL logic signal goes high 100-500 msec after main output; it
goes low at least 4 msec before loss of regulation
Requires a contact closure to disable the outputs, except 5V
standby.
Compensates for 0.5 V lead drop min. Will operate without
remote sense connected. Reverse connection protected.
