Other models 10% to 25% above nominal output CE Mark (LVD) Logical Control Power failure TTL Logic signal goes high 50 - 150 msec after 5 V output. It goes low at least 4 ms before loss of regulation Remote on/off Requires an external contact (N.O or N.C) to inhibit outputs DC - OK TTL logic goes high 50 - 150 msec after the output. It goes low when there is loss of regulation. Remote sense Compensates for 0.5 V lead drop minimum, will operate without remote sense connected.
