6U SIXHEX-16HP Description

Sealed, 0.8" pitch, high performance dry-air 6U chassis incorporates six heat exchangers, 16 super conductive heat pipes & air re-circulation fans inside. This minimum maintenance ATR is ideal for applications where ambient air is laden with hostile or harmful contaminants.

CM-ATR-45/SIXHEX-16HP

Heat is conducted to hollow sidewalls, top cover & rear panel heat exchangers where it is dissipated to the ambient environment by forced air rear fans or by vehicle air plenum. Two additional internal card-cage heat exchangers recirculate air & 16 integrated heat pipes provide fast passage for heat to exit the internal card-cage. Internal air recirculation fans ensure constant airflow across modules.

CM-ATR-S5/SIXHEX-16HP

The 6U SIXHEX-16HP chassis is available in 5, 7 & 12 slot versions (½ ATR, ¾ ATR, 1 ATR), supporting VME, cPCI, VPX, VPX-VME & cPCI-VME hybrid backplanes. Total PSU power of up to 1550 watts may be installed. Custom modifications can be designed upon customer request.

CM-ATR-45/SIXHEX-16HP Layout

Internal layout is divided into 4 independent metallic partitions. I/O section at the front, card-cage, PSU section & exhaust fans at the rear. This improves EMI/EMC performance & reduces PSU noise on system electronics.

Attention to I/O flexibility and easy board integration; allowing the intermixing of wedgelock IEEE P1101.2 conduction cooled boards, IEC-297 air cooled modules, Compact PCI 1101.1/IEC/118/ CD and VPX VITA 46.0/.1/.10/.3/.4/.7 air cooled boards.

All CM 6U ATR chassis are delivered tested, qualified and certified per Military Standards MIL-STD-461E & MIL-STD-810F.

6U SIXHEX-16HP Backplanes

CM 6U SIXHEX-16HP military backplanes are available in VPX, VMEbus, cPCI, or combinations of VPX-VME64 or cPCI-VME64 hybrids, providing standard bus slot and signal daisy-chain functionalities. Designed to improve card-cage mechanical performance with 0.8 inch pitch slots & implement many features.

CM ATR SIXHEX-16HP - 6U VME | cPCI Backpanes

All 6U backplanes install specific TTL logic circuitry for driving up to 8 front panel user LED indicators. Units fitted with a Temperature Supervisory Unit will also drive an additional panel LED TEMP (over/under temperature indicator).

  • VME64x backplanes conduction-cooled IEEE-1101.2 & air-cooled IEC-297/IEEE.1101.1 modules.
  • Compact PCI backplanes according to IEC 1076 / PCI 1101.10/IEC 48D/118/CD standards.
  • VPX backplanes conform to VITA 46.0/.1/.10/.3/.4/.7.
  • VPX-VME64x Hybrid feature mesh-fabric slots that support both VITA46 (VPX) & legacy VME64x slots.

All SIXHEX-16HP backplanes integrate a Temperature Supervisory Unit (TSU) with panel LED (over/under temperature) that controls Power Supply & Fan operation. Remote optoisolated control switches for ‘Battle-short’ & chassis PSU ‘on/standby’ are fitted & active as standard.

CM ATR SIXHEX-16HP - 6U VPX | VPX-VME Backpanes

CM 6U military backplanes allow unlimited pin I/O wiring capability. Flexible top & bottom wiring integration is facilitated by a standard 25mm bottom cavity clearance to avoid requiring a custom backplane.

Final slots in 12 & 7 slot chassis allow for bus functionality & contain power/control provisions to accept a eurocard-size metallically caged Redundant PSU. A single slot RPSU up to 575W operates in parallel with main PSU on a load-sharing basis to minimize component stress.

Custom backplanes maybe designed upon customer request.

CM backplanes support one or two 100W power sockets for optional micro-size DC/DC military converters with user defined output voltage. The converters are useful for increasing the +5VDC or +3.3VDC power lines or for generating isolated positive, negative or bipolar auxiliary DC voltages.

CM ATR SIXHEX-16HP - 6U cPCI-VME backplanes

Class 1 military power input connectors offer reliable shock & vibration interconnectivity between chassis internal modules and allows high DC current rates with low voltage drops & minimum contact heating.

6U backplanes are supplied with military conformal coating. Printed circuits boards are partially coated per MIL-I-4658C in areas in which do no affect VPX, VME, cPCI, or I/O connectors.

All 6U models integrate similar backplane electronics for easy switch-overs, retrofits or replacement parts.

6U SIXHEX-16HP Power Supplies

6U SIXHEX-16HP chassis PSUs support a wide variety of AC/DC input voltages (MIL-STD-704 & MIL-STD-1275) and customer defined DC power output combinations up to 1050 Watts. Available in different versions to suit input voltage requirments.

CM-PS-25/SIXHEX-16HP

All PSU models are fitted with Power Fail Monitor, remote voltage sensing, output voltage trim-up, time-delayed protection fuses, rear fan fuse and DC/DC converter remote shutdown.

To comply with MIL-STD-461E, a high capacity integrated EMI/EMC input voltage filter is fitted as standard on all 6U models. PSUs are custom made to match the enclosure mechanics.

200VAC 3-Phase PSU versions incorporate AC/DC rectifier stage prior to the VICOR FIAM front-end modules.

DC PSUs are equipped with a VICOR military Filter and Attenuator Module (FIAM). This front-end device is fitted prior to the DC/DC converters to provide EMI filtering, inrush current limiting and transient protection.

CM-ATR-35/SIXHEX-16HP

Front-end FIAM modules are protected against DC reverse polarity. An optional reverse polarity diode may be fitted in series with power connector input pin IN (+).

Single-phase AC PSUs are fitted with a VICOR military Filter and Autoranging Rectifier Module (FARM) to provided EMI filtering, autoranging line rectification and inrush current limiting to meet MIL-STD-461E category A1b specifications for Electromagnetic Compatibility.

6U SIXHEX-16HP PSUs incorporate isolated DC/DC converters & oversized hold-up capacitors to ensure proper operation during short power line failures. Outputs are protected against short-circuit, thermal-shutdown etc.

CM-ATR-45/SIXHEX-16HP

The PSU in SIXHEX-16HP models is attached to a heat exchanger panel that provides both conduction and convection cooling. Internal air recirculation dissipates heat generated by the PSU through its panel via thermal conduction to the chassis frame.

Forced air is drawn through the heat exchangers, passing over the PSU panel external fins & exhausted, removing the majority of heat.
