TTL logic signal goes high 100 - 500 msec after main output.
It goes low at least 4 msec before loss of regulation
Requires an external contact closure to inhibit outputs
TTL logic goes high after the output is in regulation. It goes low when there is
loss of regulation.
Compensates for 0.5 V lead drop min. Will operate without remote sense
connected. Reverse connection protected.
0° to 50 °C ambient derate each output as 2.5% per degree from
50° to 70 °C.
