Hold-up time
20ms @ 120 W load, -48 Vdc input
Overload protection
Short circuit protection on all outputs
Case overload protected @ 110 -145% above peak rating
Overvoltage protection 3.3 V output; 5 V output: 10% to 35% above nominal output
Logic Control
Power failure
TTL logic signal goes high 100-500 msec after 5 V output; it
goes low at least 4 msec before loss of regulation
Remote inhibit
Requires an external TTL Signal to inhibit outputs
Remote sense
Compensates for 0.5 V lead drop minimum, will operate with-
out remote sense connected. Reverse connection protection.
