| Features |
| Customer selectable, Multi-Inputs. |
| Wireless submodular construction for high reliability. |

| Specifications | |
| Input: | 90-130 Vac,
47-440 Hz, single phase or 3 phase (Delta, WYE) 180 to 260 Vac, 47-440 Hz, single phase or 3 phase (Delta); 200-300 Vdc. "S" version input ranges: 100- 200 Vdc. See Input Connection/Pin No. |
| Efficiency: | 65% minimum. Typically (full load, room ambient) 75% |
| Line Regulation: | Single or main: 0.1% or 10 mV, whichever is greater. Auxiliaries: for ±15V, 100mV maximum; for ±12V, 60mV maximum. |
| Load Regulation: | Single or main: 0.1% or 10 mV, whichever is greater. Auxiliaries: 150mV maximum. |
| Pard (Noise and Ripple): | 25mV rms, 100mV 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: | 1000 Vdc, input to output; 1000 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: -55ºC to +100ºC maximum, at center of the baseplate. Storage: -55ºC to +125ºC, ambient. |
| Temperature Coefficient: | 0.01% / °C maximum over entire temp range. |
| Input Transient Protection: | Unit will not be damaged or exhibit degradation of performance when subjected to input transients in accordance with MIL-STD-704A, MIL-STD-704D and MIL-STD-1399, as applicable to corresponding input configurations. |
| Load Transient Recovery: | Output voltage returns to regulation limits within 0.5 milliseconds after 50% change in load current. |
| Load Transient Overshoot: | 0.5V 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. |
| Current Limiting: | Standard. |
| Remote Sensing: | Regulator monitors voltage directly at the load using extra "sensing" leads and compensates for a dc voltage drop up to .5 volt in the load leads. (Single and main output only.) Sense pins must be tied local (at connector) or remote (at load) for proper operation. |
| Preload Requirements: | For Triple output only. A one amp minimum load is required on the main for full load capabilities on the auxiliaries. |
| 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 were designed and tested to the requirement of MIL-STD-461B, Class A1B, for generation of and susceptibility to radiated and conducted interference. For further details and reports, consult your nearest sales office. |
| Switching Frequency: | 160 to 200 kHz fixed. |
| Reliability: | MTBF is calculated per MIL-HDBK-217E at 50ºC baseplate temperature with maximum operating input voltage and maximum rated output power. The MTBF for AM50S at ground benign environment is 160,300 hours. With -ER option, MTBF was calculated to be 240,000 hours at ground benign and 25,000 for naval sheltered. |
| Environment: | Units meet MIL-STD-810D, 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.) |
