6U VME 395 Mini Chassis

The VME395 mini crate series offers hot-swappable, redundant power supplies in 9 slots, compact but modular designed VME chassis. A front-side-plug high performance DC fan is used for cooling with front to rear air flow. One or two redundant operating plug-in 250W cPCI power supplies provide sufficient power for all applications.

The VME card sized CML shelf manager allows full remote monitoring and control of power supply, fan and chassis.  The mini crate can be used on the desk either as a desktop or up-right unit or be installed in a 19” rack.
