Overload Protection

Fully protected against output overload and short circuit. Automatic

recovery upon removal of overload condition.

Overtemperature Protection

System shutdown due to excessive internal temperature, automatic reset.

Remote Sense

Total voltage compensation for cable losses with respect to the main

output.

Inhibit

TTL compatible logic signal will inhibit outputs by the application of a logic

low signal. An open circuit or external TTL high signal allows normal

operation.

Input Power

Fail Warning

TTL compatible logic signal. Time before regulation dropout due to loss of

input power at 110 VAC.

4

ms

Power Good

TTL compatible signal. Signal is low if main output is

greater or less than 10% of nominal. For models without

the “D” option, internal pull-up resistor is 1k> For “D”

option, pull-up resistor is 475. See Apps Note #P1 for

details.
