Fully protected against output overload and short circuit. Automatic recovery upon removal of overload condition.
System shutdown due to excessive internal temperature, automatic reset.
Total voltage compensation for cable losses with respect to the main output.
Accuracy of shared current with up to 6 parallel units.
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.
TTL compatible logic signal. Time before regulation dropout due to
loss of input power at 110 VAC.
TTL compatible signal. Signal is low if main output is greater or less than 10% of nominal.
Provides 170 mA current to user-supplied fan, if fan option is not selected.
