Logic Control
Power Failure TTL Logic signal goes high 100-500
msec after main output; it goes low at
least 4 ms before loss of regulation
Remote inhibit Requires a contact closure to inhibit
the outputs
Remote sense Compensates for 0.5 V lead drop min.
Will operate without remote sense
connected. Reverse connection
protected.
