CONDITIONS/DESCRIPTION
Continuous input range. Full power at 42-75 VDC.
Derate linearly from 40 VDC to 36 VDC, 400W.
Lowest DC input voltage.
At full load over DC input range.
48 VDC at full rated load.
Non-user serviceable internally located fuse.
Vin = 75 VDC, cold thermistor.
CONDITIONS/DESCRIPTION
Full rated load, 110 VAC (PFC500)/ 48VDC (PDC500).
Full load, 20 MHz bandwidth.
300 LFM forced air cooling required for operation. See optional fan.
Continuous power, multiple output models. PDC500 requires derating below
42 VDC; see PDC500 input specifications.
Output voltage overshoot/undershoot at turn-on.
Without connection of remote sense.
Recovery time, to within 1% of initial set point due to a 50-100% load change,
3% max. deviation.
Time required for initial output voltage stabilization.
Time required for output voltage to rise from 10% to 90%.
CONDITIONS/DESCRIPTION
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. For models without the
“D” option, internal pull-up resistor is 1k
pull-up resistor is 475 . See Apps Note #P1 for details.
Provides 170mA current to user supplied fan if fan option is not selected.
