Logic Control

Power Failure TTL Logic signal goes high 50-150

msec after 5 V output. It goes low at

least 3 ms before loss of regulation.
Remote inhibit Requires an external TTL high signal to

inhibit outputs.
Remote sense Compensates for 0.5 V lead drop

minimum, will operate without

remote sense connected. Reverse

connection protected.
