The VR-21 is a basic 21-slot VME system chassis. It consists of a 6U x 160mm 21-slot card cage with a VME J1 backplane, a Zoltech pow-AIR-pak power supply/fan module and a complete DC power and control cable assembly between the backplane and the pow-AIR-pak. Options include a J2 backplane, full VME control panel, desk-top enclosure, mass storage mounting panel and retaining bars for laboratory table-top use.

The basic VR-21 is designed to be mounted in a standard 19" wide rack. It can also be mounted in a Zoltech VCQE-D/D desk top enclosure for a covered look or, with Zoltech RB-x retaining bars, left fully open on a lab bench.

The pow-AIR-pak is a fully enclosed chassis that contains the power supply, fans and control panel for a card cage based system, such as the VR-21. All AC wiring is contained within the pow-AIR-pak chassis for safety.
