3100 Class Conduction Cooled ATRs

The 3100 Class Conduction Cooled ATRs is a portfolio of sealed, conduction cooled ATRs.  These ATRs meet ARINC 404A sizes (1/4 Short to 1 ½ Long).  They are also fully scalable and capable of housing all eurocard board types, form factors and slot counts.  In addition to this, these ATR chassis also utilise a machined aerospace grade aluminium alloy #6061-T651 and contain aluminium internal structures.  As a result they are strong and rigid while also ensuring MIL-STD-461 compliance for EMI/EMC.

In addition to the features listed above, these ATR chassis have been designed by NIS engineers that specialise in advance thermal management.  As a result they use the most efficient cooling methods – all based on the environment and program specifications they exist in.

Furthermore, the 3100 ATR Chassis can accommodate up to an 18-slot cPCI, VME or VPX backplane. There are also fully compliant with IEEE 1101.2 and the the internal subrack is fully machined and ready to accept various types of wedgelocks for 3U or 6U convection-cooled plug-in boards on 0.8”, 0.85” or 1.0” pitch.

Please note that power supply options include fixed or plug in style power supplies with outputs up to 2kW. Alternatively, input power options include single or three phase VAC inputs including 100-264 VAC @ 47-63 Hz; 115 VAC @ 400 Hz; and nominal VDC inputs from 12VDC up to 270VDC. Custom power systems are also available.

Finally, I/O connector options include D38999 Series-III, MIL-STD-26482 and other circular types commonly found in military electronic systems. For moderate to large unit volume, NIS will design an I/O printed circuit board to reduce cabling complexity and direct labor costs.
