Schroff Titan ATR Series is extra robust and highly flexible
For particularly high shock and vibration requirements of up to 40 g Pentair has developed the Schroff Titan ATR system family. Based on its modular 19" subracks, which is an established platform for all levels of ruggedness up to about 25 g, the Titan ATR system is suitable for civil and military aviation and space applications, including use on unmanned aircraft and helicopters, as well as other mobile equipment such as tanks or trains.
The Titan ATR system family conforms to the standardized ½ ATR short dimensions (width x depth x height: 145 mm x 328.8 mm x 193.5 mm) and offers three 3 U slots with Open VPX profile for PCIe applications. Other topologies such as VME or CompactPCI are also available. A fourth slot can hold an Ethernet switch, which enables a multiprocessor system to be installed.
The fitted backplane operates at a data transfer rate of 10 Gbit/s. It is linked directly to a transition module, eliminating the need for wiring, which tends to be susceptible to interference at the I/O connectors. The transition module is bolted directly onto the case and can be replaced easily.
The power supply unit, also supplied as standard, has an output capacity of 150 W, input voltage of 28 V, three output voltages (5 V, 3.3 V and +/- 12 V) and operates at up to 85% efficiency. The typical bridging time of 4 ms can be increased to 50 ms by means of a capacitor bank.
The Titan ATR systems can be equipped with high EMC and IP protection levels using integral gasketing. All input and output signals plus the PSU are also fitted with electrical filters. The system is thus fully shielded.
Cooling is achieved internally via conduction cooling and can be supplemented if required by forced air cooling from outside. For this purpose, the side panels are provided with cladded cooling fins, through which air is drawn from front to rear by means of a temperature controlled fan in the rear of the system. At an ambient temperature of 71 °C, the system can extract 125 W of dissipation loss and at 65 °C up to 175 W. Titan ATR systems are designed for ambient temperatures between -40 °C and +71 °C and a relative humidity of 5 to 95% (salt spray up to 5%). On request the temperature range can be extended to -50 °C to 71 °C.
Constructed in corrosion-resistant hard anodized aircraft-grade aluminum, these Titan ATR systems weigh less than 6 kg including backplane, I/O transition board and PSU. The interior of the system is also corrosion-proof thanks to a chemical coating and is electrically conductive. All boards are conformal coated to protect against environmental influences. Two options are available for mounting the systems: normal fixed mounting using bolts or the easy-to-open ARINC 404A fixing.
Based on the Schroff modular 19" platform, the Titan ATR system family can be similarly modified to customer requirements. This includes: alternative mounting options, color design, cooling options, case shape and size, adaption of transition board, filtering, PSU, etc.
