Schroff has enhanced its europacPRO range of modular subracks for use in military systems, aircraft, and power generation applications. A standard subrack consists of two side panels and at least four horizontal rails. By using stronger side panels, reinforced horizontal rails, 19inch brackets and corner profiles, the subrack is able to achieve a shock resistance up to 25g. Standard guide rails can be used in the ruggedised device, and where necessary these can be bolted to the horizontal rails. Ductings are also available to accept Card-Loks or clamshells in 0.8inch intervals and special cover plates reduce noise caused by vibration. The subrack is also available in heights from 3 to 12U and widths from 21 to 84HP and satisfies the requirements of IEC 60297-3-100 to IEC 60297-3-105 and IEEE 1101.1, 1101.10 and 1101.11.
