| Specifications |
| Input: |
103-127 Vac, 47-440 Hz,
single phase. 90-160 Vdc. |
| Efficiency: |
65% minimum. Typically
(nominal input, full load, room ambient) 70-80%. For 2.0, 3.3 and dual
5.0Vdc output modules efficiency will be 50-60% typical. |
| Line
Regulation: |
10 mV or 0.1%, whichever is
greater, over entire input range with load held constant. |
| Load
Regulation: |
10 mV or 0.1%, whichever is
greater from no load to full load with line held constant. |
| Pard (Noise and
Ripple): |
25 mV rms, 100 mV P-P for 5
Vdc output and 50 mV rms, 200 mV P-P for other voltages; measured at 25 MHz bandwidth over
temperature range. |
| Isolation
Voltage: |
700 Vdc, input to output;
500 Vdc, input to case;
200 Vdc, output to case. |
| Insulation
Resistance: |
50 Mohms between input and
output, input and case, output and case, when measured at 50 Vdc. |
| Temperature
Range: |
Operating: -55°C to +100°C
maximum, at center of the baseplate. Storage: -55°C to +125°C, ambient. |
| Temperature
Coefficient: |
0.01% / °C maximum over
entire temp range. |
| Input Transient
Protection: |
Unit will provide normal
regulated output and withstand 180 Vac for 0.1 second, in accordance with MIL-STD-704A. |
| Load Transient
Recovery: |
Output voltage returns to
regulation limits within 0.5 milliseconds after 50% change in load current. |
| Load Transient
Overshoot: |
0.5 V from nominal voltage
set point. |
| Short Circuit
Protection: |
Completely protected against
a short circuit of any duration. Output automatically restores to normal when overload is
removed. |
| Remote Sensing: |
Compensates for up to
0.5 volt drop in leads. Sense pins must be tied local (at connector) or remote (at
load) for proper operation. |
| Remote Inhibit: |
Provides for remote turn on
/ off with TTL logic signal. Application of TTL Signal (logic 1) will inhibit the outputs.
10mA required current (@5 Vdc). |
| EMI: |
Units, when tested in
accordance with MIL-STD-462, meet the majority of the requirements of MIL-STD-461C for
conducted and radiated, emission and susceptibility, for Class A1, A2 and A3 equipment for
input power leads. For further details regarding levels and extent of compliance in each
class, consult your nearest sales office. |
| Switching
Frequency: |
160 to 200 kHz fixed. |
| Environment: |
Units meet MIL-STD-810C,
altitude, shock acceleration, vibration and MIL-S-901C high-impact shock requirements.
Please consult factory for more information. |
| Hook-Up: |
Via D-Subminiature
connectors, M24308/24 type. |
| Options |
| -883 Option: |
Unit undergoes
environmental screening based upon the parameters outlined in
MIL-STD-883 and NAVMAT 4855-1. The screening consists of :
1.) Stablization Bake: +125oC for 24 hours per MIl-STD-883,
M1108 Condition B.
2.) Temperature Cycling (non-operational): 10 cycles min., at -55oC
to +125oC, 36 minute transition with 1 hour dwell at each
temperature extreme. Procedure reference MIl-STD-883, M1010, Condition B
and NAVMAT P4855-1.
3.) Long Term Operational Burn In: 160 hours of powered operation under
load. Modules are continuously cycled from +85oC to thermal
shut down point (+105oC) during the 160 hours. |
| Environmental
Stress Screening: |
Environmental Stress
Screening (ESS) including random vibration and thermal cycling per the NAVMAT guidelines
is available. Consult factory for details. |
| Ruggedized: |
COTS
readily available components are utilized. Contact factory for details. |
| -ER Option: |
Provides increased
reliability by using higher levels of military grade components.
(Not recommended for new designs.) |
