Fremont, Calif. Elma Electronic Inc. offers a low-weight commercial off-the-shelf (COTS) chassis based on the company's 12R2 model. The new 12R1 COTS version features a rugged chassis with shielding, and weighs 20 to 25% less than Elma's previous models. The new modular design also allows models to be developed in 2U and 3U heights, which was not possible in the 12R2 design.
Available in 2U to 10U heights with horizontal or vertical orientations, the COTS enclosures are designed, manufactured and tested to meet the requirements of military, aerospace and defense markets including MIL-S-167, MIL-S-810E, MIL-S-461D and MIL-S-901D standards. They are also compliant to the IEEE 1101.10/.11 mechanical specifications.
To reduce weight, some of the components for the 12R2's extreme shock
and vibration resistance of 25 Gs were excluded. However, the 12R1
withstands 15 Gs (commercial applications are sub-10 G). They are designed to withstand the harsh demands of a military environment and use honeycomb filters, braided gasketing and metal impregnated sheets to seal off all external seams. Options for shock and vibration protection include rope-coil isolators, air springs, and elastomeric isolators.
The COTS enclosures hold 6U x 160-mm or 220-mm cards and are available in 22-inch and 25-inch depths or custom sizes. They also include convenient, separate front access to drives via a removable hinge door, allowing space for drives (or Kingston carriers). A wide range of backplanes in various slot sizes is available in VME, VME64x, CompactPCI, or VXI architectures.
Other features of the 12R1 line include a large patch panel for I/O located on the rear of the chassis, two handles per side for easy lifting and power supplies for up to 750 to 1000 watts. Standard power supply voltages are ±12V, 5V, and 3.3V. Front-to-rear cooling is achieved through a Rear Evacuative Cooling system often using 2 x 470 CFM Free Air Blowers. System monitoring LEDs for DC voltages, over-temperature and fan failures are standard.
In addition, the new units offer an optional louvered front panel to meet the International Protection 53 code according to IEC 60529 for drip requirements. A clear alodine coating provides corrosion protection. Custom modifications are available.
Pricing for the 12R1 starts at less than $5,000.00. Delivery is eight to ten
