18-80 Volts dc.
MIL STD. 704E, transients as pre Fig 9, including voltage spikes
specified in MIL-E6051.
50 Mohms@100Vdc
100Mohms@200Vdc
50mohms@100Vdc
Not less than 75% at full load, 28 volts input and at 25 deg C
ambient temperature.
+/- 2% of output voltage
5% of maximum current.
50mV peak to peak max. 0 -20MHz
Output is protected against indefinite overload and short circuit.
Power limiting circuitry operates at 120-175% of full rated power.
Output voltage recovers automatically when the overload is removed.
To protect internal circuits against low input voltages, the converters
will not operate below a nominal input voltage of 15V dc.
No hold up is provided although terminal pins are provided for connection
of an external capacitor. A series diode is also required.
The units are designed to meet the following requirements of MIL STD
461C, Part 2, category A1b:
CE01, CE03, CS01, CS02, CS06, RE02, RS02, RS03.
-40 deg C to +70 deg C case temperature
-55 deg C to +100 deg C
