Two Slot 3U VPX Rackmount Chassis with RTM for Conduction Cooled Modules

VadaTech announces VTX985

Henderson, NV –  18 November, 2021 – VadaTech, a leading manufacturer of integrated systems, embedded boards, enabling software and application-ready platforms, announces the  VTX985. The VTX985 is a dual slot 3U VPX chassis conduction cooled for two 3U VPX modules. The 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. Additionally, the chassis has provision to mount to a 19” 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.

Additionally, the chassis comes with the VadaTech 4th Generation shelf manager (VT040) 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.
