VPX-VME64x Hybrid Backplanes feature mesh-fabric slots that support both VITA46 (VPX) & legacy VME64x slots. cPCI-VME Hybrid backplanes support split combinations of slot arrays that are compatible with both standards. All VPX, VME & cPCI slots support Military IEEE-1101.2 wedge-lock mechanics.Read More
CM ATR backplanes are available in 6U/3U; 5, 7 & 12 slot versions. Several custom Dual Redundant & Hybrid Backplanes are also available.
Backplanes have been designed to improve card-cage mechanical performance, incorporating active auxiliary electronics & additional options.
All chassis series incorporate True Military Monolithic Backplanes and Power Supply Units (PSU) that are custom made to match the enclosure mechanics.
Integrated backplanes are low noise, full military VMEbus, VPX or cPCI compatible and provide fully standard bus slot & signal daisy-chain functionalities.
CM backplanes support one or two 100W power sockets for optional micro-size DC/DC military converters with user defined output voltage.
These converters are useful for increasing the +5VDC or +3.3VDC power lines or for generating isolated positive, negative or bipolar auxiliary DC voltages.
All connectors in the chassis are military standard components, allowing users to easily find the corresponding mating connector on the open market.
PCB screws distributed along machined channels in front/rear locations support & minimize PCB flexing during insertion, ejection, shock & vibration events.
Backplanes incorporate extra DC electrolytic capacitors for all PSU output voltages that complement high voltage input filtering.
All CM backplanes interface the Power Fail Monitor, incorporating TTL logic circuitry for driving front panel LED indicators that are directly driven by the PSU.
Increased functions via the DC/DC redundant serial communication bus monitor; power on/off status, system board failure, correct input voltage range, bus data transfers, Temperature Supervisory Unit (TSU) with PSU shutdown & internal re-circulation fan speed control when over/under temperature.
Backplane PCB Power monitoring LEDs. Five green SMD LEDs indicate DC voltage on the TSU, +5VDC, +12VDC, -12VDC & +3.3VDC backplane power lines; three red SMD LEDs monitor when the PSU is driven to stand-by mode by the TSU.
Backplanes are supplied with military conformal coating per MIL-I-46058C in areas that do not affect connectors.
Class 1 military power connectors on PSU & Backplane offer shock & vibration reliability between chassis & internal modules, this allows high DC current rates with low voltage drops & minimum contact heating.
Integrated Reset Start Circuitry via a dedicated chip generates a 200ms pulse after power-up.
Final backplane slots in all chassis allows for bus functionality, containing power & control provisions to accept a Eurocard-size metallically caged Redundant PSU.
This single slot RPSU has the same capacity as the main PSU & both operate on a load-sharing basis to minimise component stress.
An optional TSU may be fitted for protecting card-cage electronics against extreme climate conditions, utilizing card-cage heaters & fan controls to limit the risk of high temperature failure.
The Temperature Supervisory Unit regulates chassis functions within all environments to prevent the chassis PSU overheating and aid in cold startups.
Boundaries can be easily established by the user to regulate and optimize the internal enclosure temperature.
TSU fitted units will drive an additional panel LED TEMP (over/under temperature) indicator that displays status in real time.
The TSU protects & aids in the longevity of our units by providing additional control of card-cage heaters for cold start-ups & fan speed during conditions of under and over trip point temperatures.
A delayed shut-down function to advise the CPU when power failure is imminent, allowing hard drives, relays & critical data to be shut down in an orderly manner.
Individual functions are optionally enabled or disabled by jumpers.
Remote control operation of the TSU allows the user to set the system to stand-by operation or disable the TSU. This can be utilized in situations where the ATR system is only required for a few hours but remains available on demand.
Typically, applications such as in battleships & submarines will require this feature. Note: stand-by power consumption is ≂40 Watts.
Disabling the TSU during an emergency can be carried out via a remote battle-switch to remove under/over temperature protection limits.
During battle situations it is crucial that the ATR system will remain available despite the risk of system over-stress.
