Schroff has expanded its range of VME64x system cases with the introduction of two new tower versions that are suitable for test and measurement applications. The first is a 4U-wide, 500mm-deep case that features an 8-slot VME64x system backplane and integrated 400W open-frame power supply. The second is a 5U-wide, 300mm-deep version equipped with a front-pluggable 19in power supply and a 7-slot VME64x system backplane. Both cases incorporate fan cooling with microcontroller-based fan control.
