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.
