Chassis and Backplanes<\/h1>\n<\/div>
<\/div><\/div>

Unitronix supplies rugged chassis, backplanes and accessories for embedded and defence applications. Drawing on trusted partnerships with Dawn VME and LCR Embedded Systems, we deliver modular platforms built for demanding environments \u2014 from laboratory development to full deployment. Our offerings cover VPX, SOSA-aligned and custom system architectures, including power, cooling and interconnect solutions tailored to your project requirements<\/p>\n

Don\u2019t forget the older kit, VME, cPCI are also supported, these architectures are still going and need support,\u00a0call us and let us know your problem.<\/p>\n<\/div><\/div><\/div>

Transition Module Extender Cards:\u00a0<\/strong>Extension of VME64x RTM boards from rear of backplane. Some systems have obstructions such as power supplies behind J1 which prevents direct insertion of RTM’s.
\n6U Extender Boards:\u00a0<\/strong>6U VMEbus and VME64 extension standards extender boards are primarily used to adapt the depth of a 6U board to fit into a deeper-sized card cage.
\nTest Extender Boards:\u00a0<\/strong>3U, 6U and 9U VMEbus, VME64x and Universal testing applications test and form factor extender boards. Excellent power and ground distribution.
\nPrototyping Boards:\u00a0<\/strong>3U and 6U VME, VME64x and CompactPCI prototyping boards. 0.1″ pin grid arrays allow for easy and efficient testing of your active components.

\nSlot Bypass Boards:\u00a0<\/strong>6U VME and VME64x slot bypass boards provides jumpering for BG\/IACK signals through P1. Excellent way to fill empty system slots. Air flow management can also be improved.<\/p>\n

Filler Panels:\u00a0<\/strong>3U, 6U and 9U high quality filler panels in variety of widths. Standard, IEEE1101.10 versions and customisation of standard panels. Alodine coated for maximum electrical conductivity and superior corrosion resistance. Complete with all required mounting hardware.
\nFront Panels:\u00a0<\/strong>3U, 6U and 9U high quality front panels in variety of widths. Standard, IEEE1101.10 versions and customisation of standard panels. Alodine coated for maximum electrical conductivity and superior corrosion resistance. Complete with all required mounting hardware.<\/p>\n

Overlays:\u00a0<\/strong>Adds or expands VSBbus architecture for your host VMEbus architecture. Geographical addressing is user defined at each slot. Daisy-chain jumper option accessible from overlay rear.
\nPower Busbars:\u00a0<\/strong>Dawn’s busbar sets are designed to reduce assemble time connecting +5V, +3.3V and GND to backplanes by allowing the use of one or more large wire cables rather than multiple smaller ones.
\nPower Entry Modules:\u00a0<\/strong>3U and 6U N+1 compatible 47-pin plug-in power supply power entry modules.<\/p>\n<\/div><\/div><\/div>
