OUTPUT SPECIFICATIONS
PARAMETER
Efficiency
Minimum Loads
CONDITIONS/DESCRIPTION
Full rated load, 110 VAC. Varies with distribution of loads among outputs.
Single output models.
Multiple output models, 5V main output only.
Multiple output models, 24V main output only.
Full load, 20MHz bandwidth.
300 LFM forced air cooling required for operation. See optional fan.
Continuous power, multiple output models.
Peak power, all models.
Output voltage overshoot/undershoot at turn-on.
Varies by output. Total regulation includes: line changes from 85-132 VAC or
170-264 VAC, changes in load starting at 20% load and changing to 100% load.
Recovery time, to within 1% of initial set point due to a 50-100% load change,
3% max. deviation. (Main output only on multi-output units).
Time required for initial output voltage stabilization.
Time required for output voltage to rise from 10% to 90%.

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 170mA current to user supplied fan if fan option is not selected.
