SOSA Aligned 3U VPX Benchtop DevelopmentLCR DK3 Development Platform

The DK3 for 3U VPX features an open frame concept and enhanced flexibility, with fast conversion between air and conduction cooled module guides. Fast backplane replacement makes for easy reconfiguration in support of every stage of development.

In support of a variety of test functions, the DK3’s open frame design includes backplane, power supply, fan cooling and rear transition. Backplane choices support up to twelve 3U VPX modules, with individual slots that are easily configurable to accept either conduction or air-cooled modules.
