Two slot 3U VPX chassis with RTM for conduction cooled modules

VadaTech, which has an integration centre in Southampton, has launched a dual slot 3U VPX chassis conduction cooled for two 3U VPX modules.

The VTX985 chassis can accept a front and a Rear Transition Module (RTM). The Chassis CPU will monitor and maintain the VPX module wedge temperature, set by the user which allows testing of the conduction cooled modules without going through the thermal chamber.

The chassis also has provision to mount to a 19in Rackmount and a Universal AC power supply that provides 400W to the chassis. The chassis supplies all the necessary power (+12V, -12V, +5V, +3.3V etc.) to the module in accordance with VITA 46 specifications and a battery pack is included that provides VBAT to the module. The chassis provides the current draw on the +12V, +5V and +3.3V by the VPX module and its associated RTM.

The VTX985 also has temperature control via variable speed fans controlled by the onboard CPU which keeps the wedge at the user defined temp. The backplane provides all the necessary VITA 46 signals set by the user (NVMRO, SYSRESET, SYS_CON, driver the dual clock, etc.). All the connectors are installed P0 thru P6 and are routed from the front to the rear. The unit can be ordered with custom routing between the two modules but the default routing routes all P1 ports between the two modules. The backplane also breaks-out the JTAG signals via a header connector to enable external connection of a JTAG probe.

The chassis uses VadaTech’s fourth generation shelf manager that monitors the VPX board sensors in compliance to VITA 46.11. The VT040 supports Tier 2 Health Management and comes with the VTX985 chassis.

VadaTech has headquarters, design and manufacturing facilities in Henderson, NV with design, support and sales offices in Europe and Asia Pacific.
