H12 – 1U Compact PCI / VME64x Chassis

Designed for use in either 19” rackmount or desktop applications, the H12 chassis is Verotec’s slimmest horizontal chassis. Fully compliant to IEEE 1101.10/11, the chassis is ideal for housing either VME64x or CompactPCI cards in low board count applications while still maintaining a full width rear transition capability. It is ideal for development or target/deployable systems requiring minimum space with its robust yet cost-effective design. System cooling is optimised for efficiency with a push-pull configuration, providing sufficient cooling for the demanding requirements of the latest CPU boards when used in a 1U form factor system. The top cover can easily be removed to provide excellent access, ideal for testing and development activities.

Thermal Management

The system airflow for the cards is from right to left, using a push-pull configuration. Three exhaust fans are fitted on the left hand side, covering both the front and rear card cages, while two fans draw air from the front and right hand side. Each fan is rated at 7.5 cfm in free air, providing the board cooling while the PSU is fitted with its own cooling fan, exhausting to the rear of the unit.

Power Supply

Fitted with an autoranging ATX style embedded power supply with active Power Factor Correction, which is capable of providing a combined 110W on the 5V and 3.3V rails while offering full short circuit and over voltage protection. A front panel on/off switch is also provided.


Good EMC shielding is achieved by adopting proven design practices. These include conductive fabric-over-foam gaskets on fixed seals and Beryllium Copper gaskets on the card cage apertures. The airflow vent patterns are 3.5mm round holes on a 5mm triangular pitch.


The chassis is available with either a CompactPCI or VME64 extensions backplane. The CPCI option is a 6U, 2 slot, 64 bit, PICMG2.0 R3.0 compliant backplane with a right-hand system slot (top of system), with rear plug-up connectors in P3,P4 & P5 and selectable coded I/O voltage (default = 5V). The VME64x version is a 2 slot ANSI/VITA 1.1 – 1997 compliant backplane fitted with active on-board termination, electronic ABG (auto bus grant) and centre P0/J0 connectors fitted.
