CONDITIONS/DESCRIPTION
Continuous input range.
AC input.
After last AC line peak at 400 watts.
85 VAC at full rated load.
Non-user serviceable internally located AC input line fuse.
Internally limited by thermistor. Vin = 220 VAC, one cycle, 25°C.
Per EN61000-3-2 (Over the entire input range and above 60W load).
CONDITIONS/DESCRIPTION
Full Rated Load, 115 VAC. Varies with distribution of loads among outputs.
Full load, 20 MHz bandwidth.
With 460 LFM forced-air cooling (25 CFM through the power supply opening),
V1+V2+V3+V4+V5:
V1+V2 or V3+V4:
Output voltage overshoot/undershoot at turn-on.
Varies by output. Regulation includes: line changes over the specified
input range and changes in load between 0% and 100% load.
Recovery time, to within 1% of initial set point due to a 50% load change in
the load range of 10 to 100%; 3.5% or 100mV deviation, whichever is greater.
Time required for initial output voltage stabilization.
Time required for output voltage to rise from 10% to 90%.
CONDITIONS/DESCRIPTION
Overvoltage protection on all outputs except V5.
Unit latches off when overvoltage is detected.
AC input must be recycled to reset. V5 is protected by a 6.2V ±5%, 2W Zener diode.
Fully protected against output overload and short circuit. Automatic recovery upon
removal of overload condition. All outputs are individually current limited.
Power supply shuts down due to excessive internal overtemperature at the output
converter’s primary switching transistors. Power supply resets automatically upon
removal of the overtemperature cause.
TTL-compatible global Output Good signal. The signal is active when any of the
V1-V4 outputs drop >14% below nominal. Source impedance is 1k .
Open collector signal. Time before regulation dropout due to loss of input
power. May be used as independent PSOK signal in redundant applications.
Available on all outputs except V5. Accuracy of shared current with up
to two parallel units. Single wire current share is provided. For paralleling
more than two units, consult factory.
Available on all outputs except V5. Total voltage compensation for cable losses with
respect to the main output.
