Input Voltage Range: 18-80 Volts dc

DC Output: 5V at 2Amps
Input Power Characteristics: MIL STD. 704E, transients as pre Fig 9, including voltage spikes
specified in MIL-E6051.
Isolation: 

Input to Output 50 Mohms@100Vdc
Input to Chassis 100 Mohms@200Vdc
Output to Chassis 50 Mohms@100Vdc
Efficiency: Not less than 75% at full load, 28 volts input and at 25 deg C ambient temperature.
Load Line and Temperature Regulation: +/- 2% of output voltage
Minimum Load Condition: 5% of maximum current.
Ripple and Noise: 50mV peak to peak max. 0 -20MHz
Output Protection: 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.
Under Voltage Lockout: To protect internal circuits against low input voltages, the converters will not operate below a nominal input voltage of 15V dc.
Hold Up: No hold up is provided although terminal pins are provided for connection of an external capacitor. A series diode is also required.
EMI: 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.
Operating Temperature: 40 deg C to +70 deg C case temperature
Storage Temperature: -55 deg C to +100 deg C
Weight: 100 grms.
MTBF: 100,000 Hours / AIF 50 deg. C
