Electronics enclosure manufacturer Schroff has introduced a new range of rugged 19in. cabinets that have been specifically developed to handle the rigorous demands of underground railway applications. Utilising an innovative cable-channel design, the Varistar cabinet achieves an impressive EMC performance while significantly reducing installation time by allowing existing cable assemblies to be routed into the cabinet without the need for retermination.

Offering a static load-carrying capacity of up to 800kg, the cabinet features a closed rolled-steel frame construction for high stability and excellent resistance to shock and vibration. Tests carried out in accordance with IEC 61587-1 indicate a shock resistance of up to 5 g and an earthquake resistance up to Bellcore Zone 4.

The new range includes standard configured cabinets in two sizes of 38U and 43U. The smaller version has overall dimensions of 1800mm high x 600mm wide x 600mm deep and features a single 100mm x 100mm cable channel. Equipped with a 48VDC fan tray, it can be specified with or without battery shelves.

The larger 43U model measures 2000mm high x 600mm wide x 800mm deep and has a double cable channel, which makes it particularly suitable for use where numerous cables need to be fed into the cabinet. This model is equipped with a 230VAC fan tray.
Front and rear doors are vented and fitted with dust filters, and the cabinets are finished in LUL-approved LSHF (low smoke, halogen free) light grey paint. All plastic parts carry a
UL 94 V-0 flammability rating.
