| Specifications | |
| Input: | 14-32 Vdc |
| Efficiency: | 65% minimum. Typically (nominal input, full load, room ambient) 70-80%. For dual 5Vdc 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): | 25mV rms, 100mV P-P at 25 MHz bandwidth, measured over temperature range. |
| Isolation Voltage: | 500 Vdc, input to output; 400 Vdc, input to case; 100 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 50 Vdc for 0.1 second, in accordance with MIL-STD-704D. Compliance to MIL-STD-704A (80 Vdc for 0.1 second) can be achieved with optional transient suppression module. Contact factory for details. |
| 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.) |
