The new industrial subrack is available in two versions - one version is prepared to accommodate a backplane, while the other is designed for the use of connectors. Fitted with a suitable backplane, power supply unit and ventilation unit, this subrack can be used, for example, as a small CompactPCI system with up to five plug-in boards. The mounting brackets of the subrack feature keyholes for easy fixing to the mounting plate on which appropriate bolts or screws are provided. The subrack is available with or without a rear hood. A drilled plate is inserted to provide a top cover. A bolt-on cover plate is also available as an option.
