DC to DC Converter for Aircraft Applications PSA-2
- RTCA DO160 QUALIFIED
- WIDE INPUT RANGE
- MEETS MIL-STD-704
- FULLY ISOLATED
28 VDC nominal. Meets MIL-STD-704, Continuous operation from 18 to 40 VDC.
±1% of nominal over the full range of line input voltage.
±1% for change from no load to full load.
5 VDC nominal and 6.8 VDC max in overvoltage.
1A nominal (limited to 1.4A even when short circuited)
OPERATING TEMPERATURE RANGE:
Storage, transport ation and handling: -62 ° to +72 °C.
Ambient temperature: -20 °C to +70 °C baseplate.
The input power circuits and DC output voltage lines are isolated from the chassis.
20 Megaohms or greater between individually insulated terminals and between all terminals and the case when tested at 500 VDC.
SHORT CIRCUIT PROTECTION:
Each unit is completely protected against a short circuit of any duration. The constant current circuit is nominally set at 120% of full load to reduce voltage. The output voltage automatically restores to normal when the short is removed.
DIELECTRIC WITHSTANDING VOLTAGE:
1500 V AC RMS, 60 Hz between all terminals and the case, for 1 minute, without any leakage current in excess of 1mA or evidence of damage due to arcing or insulation breakdown.
MTBF 109,434 hours calculated per MIL-HDBK-217F Notice 2 in ground mobile applications.
All units are qualified per RTCA DO 160.
