LCR AoC-850 ATR chassis conduction cooling with air assistAoC3U-1400 Advanced Thermal Performance for High Slot Count VPX Systems

Part of our line of conduction cooled enclosures with air assist, the AoC3U-1400 is designed to maintain safe operating temperatures for high slot count 3U VPX systems. The base design includes dual 9 slot backplanes for up to 14 payload modules plus 2 each VITA 62 power modules and power hold up modules. The MILSTD-1275 and 704 power supplies ensure continuous operation in demanding air, land and sea applications where power and environmental challenges exist. Backplane slots include VPX and SOSA aligned profiles supporting high speed signal processing applications. High cfm fan banks provide forced air cooling to widely available VITA 48.2 conduction cooled board sets with aggregate power demands approaching 850W, ambient environment dependent. This precision engineered packaging solution is intended for mission critical defense applications and is designed to meet a wide range of MIL-STD-810H requirements and test methods
