6U HES-1 Description
Sealed, 1" pitch, high performance dry-air 6U chassis incorporates four heat exchangers and air re-circulation fans inside. This minimum maintenance ATR is ideal for applications where ambient air is laden with hostile or harmful contaminants.
Heat generated within the enclosure is conducted to the hollow sidewalls, top cover & rear panel heat exchanger where it is dissipated to the ambient environment by forced air rear fans or by vehicle platform air plenum. Internal air recirculation fans ensure constant airflow across modules.
CM-ATR-S5/HES
The 6U HES-1 chassis is available in 5 & 7 slot versions (½ ATR, ¾ ATR, 1 ATR), supporting VME, cPCI, VPX, VPX-VME & cPCI-VME hybrid backplanes. Total PSU power of up to 825 watts may be installed. Custom modifications can be designed upon request.
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.
This 1" pitch chassis has been designed exclusively for VME wedgelock IEEE P1101.2, Compact PCI 1101.2/IEC/118/ CD and VPX VITA 46.0/.1/.10/.3/.4/.7 conduction cooled modules. A mixed card-cage, supporting air-cooled and conduction-cooled modules my be selected upon request.
6U HES-1 Performance
The 6U HES-1 chassis is suitable for high wattage sealed applications that demand superior cooling capability.
HES-1 - Chassis Global Thermal Resistance (CGTR) coefficient:
ΔT/W = 0.084°C (½ ATR) | 0.077°C (¾ ATR).
HES-1 - Chassis Payload Thermal Resistance (CPTR) coefficient:
ΔT/W = 0.0924°C (½ ATR) | 0.0847°C (¾ ATR).
For reliable operation it is recommended the maximum Payload Power not be exceeded. Subject to operating conditions.
All CM 6U ATR chassis are delivered tested, qualified and certified per Military Standards MIL-STD-461E & MIL-STD-810F.
6U HES-1 Backplanes
CM 6U HES-1 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. HES-1 backplanes are 1" pitch & deliver full compatibility with 0.8" pitch modules.
All 6U backplanes install specific TTL logic circuitry for driving up to 8 front panel user LED indicators. HES-1 backplanes are fitted with a Temperature Supervisory Unit and 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 HES-1 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 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.
The final slot in HES-1 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.
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.
