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
Safety
VDE UL CSA NEMKO CB CE 0805/EN60950 (IEC950) UL1950 CSA 22.2-234 Level 3 EN 60950/EMKO-TUE (74-sec) 203 Certificate and report Mark (LVD)
Power failure Remote inhibit Remote sense
TTL logic signal goes high 100-500 msec after 5 V output; it goes low at least 4 msec before loss of regulation Requires an external TTL Signal to inhibit outputs Compensates for 0.5 V lead drop minimum, will operate without remote sense connected. Reverse connection protection.
