6U VME 195 Mini Chassis

The VME195 mini crate is the perfect choice for small setups with only a few VME modules. The crate offers 9 VME slots in a compact designed chassis with integrated low noise power supply and cooling fan. The mini crate can be used on the desk either as a desktop or up-right unit or be installed in a 19” rack.

Based on the 6000 series it has a built-in microprocessor controlled low-noise power supply technology and provides all local and remote monitoring and control features.


  • VME-MINI-Bin mechanics for 6U 160mm VME modules, suitable either for 19″ racks, as tower- or desktop box
  • 9 slot monolithic backplane VME/VME64
  • Free rear access for 6U transition modules, standard transition cage for 6U 160mm modules, provisions for 80 and 120mm foreseen. Special depth on request
  • Front and rear cover / screen for module space, cable duct between front- and rear-side of the card cages with space for one or more 2.5″ hard / floppy-disks
  • Micro-processor controlled with alphanumeric high-visibility LED display, 4 status LED’s
  • Efficient DC blower, adjustable speed (1200 … 3200 RPM)
  • Integrated fan and thermal monitoring ( 8 temperature sensor ports, 5 ports free for custom applications) with temperature display (C/F), programmable over temperature protection
  • Ethernet  interface  for crate remote monitoring and control
  • Built-in power supply designed in low noise VHF switching technology, noise and ripple typically less than 10mV(pp) or 3mV(rms) , CE-conformity
  • 94V – 265V world-wide auto-range AC input, with power factor correction, CE-conformity
  • Dimensions: 19” (482mm)  x 5U (178mm) x 480mm [whd], weight: ca. 25 kg
