The 3000 Series Convection Cooled ATRs is a portfolio of convection cooled ATRs that conform to standard ARINC 404A sizes (1/4 short to 1 1/2 long).  These ATRs are also fully scalable and capable of housing all euro card board types, form factors and slot counts.  In addition to being meeting ARINC standards, these ATRs also have machined aerospace grade aluminium alloy housing and aluminium internal structures.  As a result, they provide superior strength and rigidity while also ensuring MIL-STD-461 compliance for EMI/EMC.

In addition to this, because NIS engineering specialises in advanced thermal management and packaging techniques;  the most efficient cooling methods (based on environment and program specifications are first considered in the design process.  As a result, the 3000 convection cooled ATRs provide aggressive cooling from forced air – generally blowing through front to rear air channels.

Furthermore, the Class 3000 ATRs also accommodate up to 18-slot cPCI, VME or VPX backplane.  These chassis are also fully compliant with IEEE 1101.10.  In addition to this, the internal sub-rack consists of NIS’s single-piece billet for added structural strength.  Finally, these ATRs also accept 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. 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, passing those savings to you, our customer.
