Case overload protected CE: Mark (LVD) 115 - 130% above peak rating Overvoltage protection 20 - 35% above nominal outputNTS500-M Series Data Sheet Logic 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 Remote on/off Requires an external contact closure to inhibit outputs DC OK TTL logic goes high after the output is in regulation. It goes low when there is loss of regulation. Remote sense Compensates for 0.5 V lead drop min. Will operate without remote sense connected. Reverse connection protected.
